3 3 6 Design Title benefits Proven design FLSmidth Krebs s Technequip TGW series wafer style knife gate valve has been specifically designed as a space-saving option for heavy duty applications. The long-lasting replaceable elastomer sleeves offer a reliable sealing solution using the latest technology. Reliable operation The full port design allows the gate to be fully isolated by the sleeves from the process in the open position. As the gate closes, it pushes between the two sleeves, discharging a small amount of material out of the bottom of the valve. This serves to prevent material buildup in the seat area to ensure a full gate closure, as well as to prevent damage to the gate. When the gate is in the open or closed position, there is a 100% bi-directional bubble tight seal and zero downstream leakage. Long life All valves are supplied with dust boots (bellows) as standard to protect valve stems and actuators. All manual and electro-mechanical valves are also supplied with stem covers as standard for additional stem and actuator protection. All valves are fully lined ensuring no metal comes in contact with slurry flow. All valves are supplied with special zinc-plated hardware (nuts, bolts, and washers) for corrosion protection. Each component is individually epoxy painted prior to assembly.

5 5 8 Actuation Title options Air cylinder - double acting (AC) Technequip valves are available with double acting pneumatic actuators in sizes 2 (50mm) to 24 (600mm). All actuators supplied are Parker VE Series actuators suitable for a minimum of 75 psi (5.2 bar) plant air. The air cylinders are manufactured with steel end caps, and a chrome-plated piston rod and are attached to the gate with a machined 17-4 PH SS gate clevis. For superior wear life and reliability, the cylinder tube is constructed of Amalga Composites Black Amalgon fiber reinforced thermoset epoxy matrix tubing. All air cylinders are supplied as standard with an internal ring magnet in the piston, so that they can be used with optional externally mounted reed limit switches. A dust boot is supplied as standard. For applications with low or unreliable plant air, an oversized air cylinder that is suitable for a minimum of 60 psi (4.1 bar) air, can be supplied for valves sized 2 (50mm) to 24 (600mm). Also available are single-acting, spring-return air cylinders for sizes 2 (50mm) to 14 (350mm). These are available in Fail Open and Fail Close, when this action is required on loss of air. For specific pneumatic requirements not listed, please contact the factory. Hydraulic- double acting (HYD) Technequip valves are available with double acting hydraulic actuators in all sizes. All hydraulic actuators supplied are Parker 3L Series actuators. The hydraulic cylinders are manufactured with steel end caps, chromeplated piston rod, and bronze gland rod, and are attached to the gate with a machined 17-4 PH SS gate clevis. A dust boot is supplied as standard. Electric (ELEC) Technequip valves are available with electric actuators for all sizes. Electric actuators can be specified as Limitorque, AUMA, and Rotork, and can be supplied to meet numerous voltage requirements. All electrically actuated valves are supplied with a 304 SS stem, protected by a stem cover and dust boot. Bevel gear - double acting (BG) Technequip valves are available with bevel gear actuators in sizes 6 (150mm) to 24 (600mm). All bevel gear operators are manufactured by Dynatorque. Supplied where manual actuation is required, but the rim pull of a handwheel actuator would be too high. Caution is advised on the larger sizes due to the large number of turns required to open and close the valves. All bevel gear valves are supplied with a 304 SS stem, protected by a stem cover and dust boot. Hand Wheel (HW) Technequip valves are available with hand wheel operators in sizes 2 (50mm) to 10 (250mm). For sizes larger than 10 (250mm), the rim pull is too high for a handwheel valve, and a bevel gear valve is recommended where manual actuation is required. All handwheel valves come standard with a 304 SS stem, protected by a stem cover and dust boot. As an option, hydraulic power units, or hydraulic hand pumps can be supplied.

7 7 4 Wafer Title style valve specification Technequip TGW Series Knife Gate Valve: narrow body, slurry knife gate valves are designed specifically for slurry applications. The valves are bi-directional with a full port design. The valve body is designed such that the gate passes between two inserted elastomer sleeves which allows solids in the path of the gate to be expelled through the opening in the bottom of the valve. Flush ports have been added to the valve housing to assist in keeping the gate area free of debris. The valve design is packing-less. The valve provides 100% bubble-tight seal in the open and closed position. The valve is constructed of two-coat epoxy-painted steel or ductile iron. Valve bodies are designed with machined gate guides; spacer bars are not used. Valve components, including actuators, are individually epoxy coated prior to assembly. All hardware is zinc-plated. Standard valve gate material is 17-4 PH stainless steel. Gates are coated with a fluorocarbon coating to prevent buildup of material and to decrease friction between the gate and the sleeves. When open, the gate is fully removed from the flow. Valve gate is attached to actuator with a high-strength stainless steel gate clevis. The valve is equipped with a dust boot (bellows) and all manual and electric valves are equipped with a stem cover. The valve gate and body are designed with a wiper/seal to prevent leakage out the top of the gate valve during actuation. The wiper blade is easily maintained. It is replaceable in the field, without removing the valve from its installed location. All valves with pneumatic actuators are supplied with internal ring magnet integral to the piston head so that reed limit switches can be used for proximity indication.
