w w w. g w c i t a l i a. c o m API 6D THROUGH CONDUIT SLAB GATE VALVE standard features Standard Features and Benefits 1. Seats / Fire-Safe Design (See Figure A) Depending upon the service of the valve, the seats can be supplied with soft seat inserts / hard face deposited metal seats. The line pressure / springs / energized O-rings, assists the single piston effect designed seats for high / low pressure sealing against the slab gate face, ensuring that a tight seal is formed. The soft seats and the seat pockets have been designed to be fire-safe. During a fire, the soft seats can be destroyed. As the seats are being slowly burnt, the upstream pressure forces the slab gate against the downstream seat. The downstream seat is thereby forced against the back of the seat pocket. The downstream seat is now forming a metal-to-metal seal with the back of the seat pocket face. When the soft seats have been fully burnt, the metal face of the seat now forms a metal-to-metal seal with the slab gate. Metal seated seats are firesafe by design. 2: Double Block and Bleed (See Figure A) The double block feature is the result of the two seats sealing against the slab gate, with the valve in the fully closed position, whether the line is under pressure or not. When there is no pressure on either side of the seats, the springs / energized O-rings force the seats to form a tight seal on the upstream / downstream sides of the slab gate. When there is pressure in the line, the upstream pressure forces the slab gate against the downstream seat, whilst also forcing the upstream seat against the slab gate, due to the single piston effect design of the seats. This has now formed a tight seal or double block on both sides of the slab gate. With the slab gate now tightly sealed on both sides, the vent / drain plug in the body can be released which will bleed the body cavity of pressure. This feature allows the draining of the cavity to remove debris / take a sample of the medium / test the sealing integrity of the seats. 3: Automatic Cavity Relief (See Figure B) Should the pressure in the body cavity exceed the line pressure, due to thermal expansion caused by an internal / external heat source, the greater cavity pressure will push the seat off the slab gate face allowing the excess cavity pressure to be vented into the line. This feature ensures that there is pressure equilibrium between the line and body cavity, which prevents the body material becoming overstressed. 4: Seat Sealant Injection (See Figure C & D) Due to possible damage of the seats by debris in the line / stem O-ring failure due to a prolonged service, there can be leakage from these areas. To extend the service life of the valve until the valve can be removed from the line for repair, a sealant can be injected through the seat / stem injection fittings.

w w w. g w c i t a l i a. c o m API 6D THROUGH CONDUIT PARALLEL EXPANDING GATE VALVE standard features Standard Features and Benefits 1: Seats/Fire-Safe Design (See Figure A) Depending upon the service of the valve, the seats can be supplied with soft seat inserts / hard face deposited metal seats. As the sealing action of the valve is mechanically activated, line pressure is not required to force the seats against the expanding gate. Therefore, the seats are of a very basic, but rugged design. The soft seats and the seat pockets have been designed to be fire-safe. The sealing action of the fire-safe design is the same as that of the slab gate valve. Metal seated seats are fire-safe by design. Figure A 2. Double Block and Bleed (See Figure A) The double block feature is the result of the two seats sealing against the expanding gate, with the valve in the fully closed position, whether the line is under pressure or not. When there is no pressure on either side of the seats, the springs / energized O-rings force the seats to form a tight seal on the upstream / downstream sides of the expanding gate. When there is pressure in the line, the upstream pressure forces the expanding gate against the downstream seat, whilst also forcing the upstream seat against the expanding gate, due to the single piston effect design of the seats. This has now formed a tight seal or double block on both sides of the expanding gate. With the expanding gate now tightly sealed on both sides, the vent / drain plug in the body can be released which will bleed the body cavity of pressure. This feature allows the draining of the cavity to remove debris / take a sample of the medium / test the sealing integrity of the seats. Figure C Figure- C 3.

GWC ITALIA Proven technology for individual valve solutions worldwide API 6D THROUGH CONDUIT PARALLEL EXPANDING GATE VALVE Operation Principles Figure E Figure F Figure G Closed Position: Gate Assembly Fully Expanded (See Figure E) As the gate and segment assembly are approaching the closed position, the stopper on the segment has contacted with the lower body stop, which prevents the segment from travelling any further. As the hand wheel is turned further, the main gate is forced down and against the wedge angle of the segment. This action expands the gate and segment assembly against the seats to form a tight seal. Mid Travel Position: Gate Assembly Fully Retracted (See Figure F) As the hand wheel is turned to open the valve, the gate travels up and away from the wedge angle of the segment. This action retracts the gate and segment assembly sealing force from the seats, which allows the assembly to travel freely between the seats. From the fully open to the fully closed positions, a gate centralizing mechanism holds the gate and segment assembly in the fully retracted position, to ensure that the assembly does not wedge itself between the seats. Open Position: Gate Assembly Fully Expanded (See Figure G) As the gate and segment assembly are approaching the open position, the stopper on the segment has contacted with the upper body stop, which prevents the segment from travelling any further. As the hand wheel is turned further, the main gate is forced up and against the wedge angle of the segment. This action expands the gate and segment assembly against the seats to form a tight seal to isolate the flow from the body cavity. At this position, the bore holes of the gate and segment are aligned exactly with the valve bore. 14
w w w. g w c i t a l i a. c o m API 6D THROUGH CONDUIT PARALLEL EXPANDING GATE VALVE Gate Centralizer Operation Principles Figure H Figure I The main purpose of the gate centralizer is to maintain the gate and segment assembly in the fully retracted position, during the travel from open to close, to prevent any wedging action between the assembly and the seats (See Figure H) However, the gate centralizer allows the gate and segment assembly to expand at the final moment. During the travel from open to close, the gate centralizer is maintained in a parallel position with the seats by the skirt plates, which are positioned either side of the seats (See Figure I) As the gate and segment assembly are nearing the fully open / closed positions, the skirt plates allow the gate centralizer to tilt, which allows the gate and segment assembly to expand. The skirt plates also assist in aligning the gate and segment assembly with the seats (See Figure J) Figure J 15
GWC ITALIA Proven technology for individual valve solutions worldwide API 6D THROUGH CONDUIT PARALLEL EXPANDING GATE VALVE Body Cavity Pressure Relief Figure K Figure L Due to the design of the expanding gate and seats to form a tight seal, any excess pressure build-up in the body cavity can t be self-relieved, as in the slab gate design. To relieve this body cavity pressure, 2 types of a pressure relief system can be provided on the outside of the valve body. The standard type consists of 2 needle valves, a check valve, tubing and fittings. This system relieves the body cavity pressure to the upstream side of the valve. During normal valve operation, the 2 needle valves must be kept open, so that the upstream line pressure can keep the check valve closed. When the body cavity pressure exceeds the upstream line pressure, the check valve is un-seated and the excess pressure is relieved upstream (See Figure K) The other type of pressure relief system is a safety pressure relief valve fitted on the outside of the valve body. A drilled and threaded hole connects the body cavity to the safety pressure relief valve. The safety pressure relief valve is set to relieve pressure at 1.33 times the line pressure, or as per the clients requirements (See Figure L) 16
