Swing Check Valve bodies are ordinary hinge, there is a door the same as the free flap valve against the valve seat sloping surface. In order to ensure that every valve seat surface to reach the appropriate position in the valve hinge design in order to have a valve Swing have sufficient space and the real valve, all-round contact with the valve seat. Valve could be made of metal can also be embedded in the metal on leather, rubber, or synthetic coverage, depending on the use of performance requirements. Swing Check Valve fully opened in the circumstances, almost unimpeded fluid pressure, so the pressure drop through the valve is relatively small.Our Features ENO Valves Cast Steel Ball Valves have been designed to meet the requirements BS 5351/ASME B 16.34API 6D-ISO 14313/API 608/MSS SP 72 Face to Face and End to End dimensions conform to ASME B 16.10 / ISO 5752 / BS 2080 /API 6D-ISO 14313/ DIN End flange dimensions conform to ASME B 16.5 / ISO 7005-1 / API 605 / BS 3293 / DIN Butt weld end dimensions conform to ASME B 16.25 Fire tested design to API 607/API 6FA/BS 6755-II Flexible lip seats compensate for wear and changes in pressure Blow out proof stem construction Antistatic devices ensure electrical continuity between ball, stem & body ISO 5211 top pad for simplified gear/actuator mounting Valves meet the requirements of fugitive emission levels Shell category B as per MESC SPE 77/312 One, two or three piece construction For low temperature and cryogenic services extended bonnet as per BS 6364 available Locking arrangement Gear, Electrical, Hydraulic or Pneumatic actuator available Soft seats are recommended for service temperature up to 260 Deg.C and for higher temperatures a metal to metal seating offered Can be supplied with GRAYLOC END HUB, under project license from GRAYLOC PRODUCTS.
