Quick Release Couplings – Single Check Valve
BOSTAN ENGINEERING (BE LOCK): was established in 2006, We are manufacturing Quick Release Couplings also known as Quick Connect / Disconnect Couplings. After a successful designing of couplings highest quality by testing products up to 1000 bar pressure is being continued to manufacture and is being supplied to customers in India as well as customer in abroad.
What is QRC: Quick release couplings are fitting are used to mate fluid lines with system equipment that requires frequent connecting and disconnecting. They are used in both pneumatic and hydraulic applications to build or discontinue the connection of a fluid pipeline.
Type BE-QRC-SCV (Single Check Valve) is most popular type coupler used to connect air piping in factories and used to connect air tools with hoses etc. Both socket and plug have hose use and screw use advantages. There is also a variety of other types. The types 20, 30, 40, and Types 400 and 600 are completely interchangeable. With one check valve built into the coupling only whereas plugs do not have any check valves. Can be advantageously used where one side of the flow system needs to be sealed on disconnection.
Seal components: Nitrile (Buna-N) seals are standard, providing a temperature range of – 40 C (- 40 F) to +121 C (250 F). Couplers have a PTFE Anti-Extrusion ring. Valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurised connection.
Materials: Machined components are manufactured using solid steel bar stock. Stainless steel balls, retaining rings and springs maximize corrosion resistance and extend service life. Steel componentry is plated using ROHS complaint trivalent chrome. Steel coupler sleeves are hardened to resist deformation and maximise service life. Steel nipples are hardened to provide heavy duty performance.
Application: For leak-proof handling of process line, chemicals, gases, liquids, hydraulics and service lines like compressed air, steam water, vacuum, brine, chilled water, nitrogen, breathing air etc. in chemical, refineries, fertiliser, atomic power plants, pharmaceutical, engg., machine tool, automobile, paint, dye-stuff & varnish, petroleum, furnaces, textile machines, refrigeration industries.
Coupler handling precautions:
- Avoid Connection and disconnecting the coupler when pressure is applied to preclude possible accident.
- Coupler has been designed to ensure complete safety, however avoid subjecting it to shock.
- Remove foreign matter from the Fluid with a filter beforehand. If Foreign matter mixed in the fluid, operation of the internal valve will be adversely affected, causing leakage.
- Do not weld the coupler directly to Panels and fixtures. This damage the internal seal causing leakage and imperfect flow.
- When disconnecting the coupler in dusty and sandy locations, always use the specified dust cap.
- Never tap the valve section with a hammer, etc. to bleed residual pressure.
