BWX SERIES BUTTERFLY VALVE

Transcription

1 BWX SERIES BUERFL VLVE he BWX series butterfly valve has been especially designed for a wide range of industrial applications. It can be used for standard temperature up to 425 C with CS-body material as well as in cryogenic applications with high quality Cri steel. High efficiency by high flow capacity and low torques combined with fast maintenance capabilities, safety and reliable performance are main highlights of this valve series. he compact design of the valve permits rapid temperature balance and minimizes especially in cryogenic cool down processes the boil off loss. FEURES Innovative design with free floating metallic seat rotected seat in area of lowest tear and wear High flow rates emperature range: C optional up to 600 C depending on material selection Best for oxygen service Oil & grease free assembly and test B tested nonmetallic parts Differential pressure/temperature ratings in accordance with SE B16.34 DI/E flange drilling available Body types Lug and Double flange, other as option Cover plate for standard temperature For cryogenic applications 3 different standard extension lengths Body he valve body is available as lug or double flange design as standard. Other body types or special face-to-face dimensions as well as butt welded ends are available as option. he body is a monolithic design without a clamp ring. his means high safety even under full pressure with open pipe end, no additional parts and no screws in gasket flange face area. Disc he standard disc is made of a high quality stainless steel or a high strength martensitic steel, and has an innovative design, which brings a perfect and reliable seat performance with long life endurance. Shaft and drive shaft design he BWX butterfly valve has a stub shaft design and full bore port which gives a high flow coefficient. robust and easy shaft to disc polygon connection requires no additional fasteners inside the flow area and guarantees a fast and effective maintenance of the entire valve. It is practically free of play and exceeds the strength of the top of the shaft. visible mark at the shaft clearly indicates the position of the disc. High safety factor has been included to the bearing design. he thrust bearing is protected from the flow, located in the body neck and realizes the blow out protection of the shaft. he gland packing is live loaded to ensure minimum emissions and is located directly after the upper shaft bearing which prevents any side forces from the packing. Low cost of ownership Significantly reduced number of parts reduce stock keeping cost of spares. Extremely high cycle life minimizes the need of maintenance and increases ean ime Between Failure (BF) aintenance friendly design allows a very fast dis- and reassemble of the valve without special tools. 2 BWX 20 E 8/2016

2 ESO 2 BWX 20 E Seat he BWX series is equipped with a floating full metal seat located independently in the body. dditionally the seat is protected in the body in an area of lowest wear and tear. his design principle ensures high duration with constant, repeatable and reliable tightness performance even during rapid temperature changes and differentials within the valve. he innovative design gives low operating torques and clears the disc from seat after a few degrees of opening which extends the life of the BWX valve. Cold shock test Besides available standard leakage a cold shock test can be performed. his test demonstrates the excellent and repeatable valve performance under real cryogenic operating conditions. he valve is cooled down with liquid nitrogen. When the valve has reached -196 C, the valve is closed and pressure is applied. Leakage if any can be monitored. cceptance criteria is no visible leakage. Oxygen service certified cleaning procedure in a special clean environment guarantees absolutely free of oil and grease parts for oxygen applications. his means that due design features the valves does not require any kind of grease during assembly and testing procedure. dditionally the flow area does neither contain any bolts, pins or nuts nor any sharp edges or corners. ll nonmetallic parts are B tested under pure gaseous or liquid oxygen up to rated pressure. ctuator he BWX valve series is equipped with a ISO 5211 mounting face to the actuator. eles pneumatic or manual gear actuators are used as standard. ositioners can be used optional. he following table gives a rough overview for BWX valves equipped with standard B1 actuators at full rated pressure.
