Quick Release Couplings – Double 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-DCV (Double Check Valve) Since both the plug and socket have a value, there is no leakage of gas, oil, etc. from either the socket or plug ends when disconnected. Since they are manufactured by an especially high precision machining process, air tightness is a high 10-4 mmHg / sec. The hose does not twist. Designed for use in a wide range of applications. The valve of the socket and plug is pushed against the valve seat and closed automatically. There is no leakage of the fluid. The valves of the socket and plug are pushed against each other, the interior of the coupling is opened, and the outside of the plug and there is no leakage to the outside.
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:
- Never tap the valve section with a hammer, etc. to bleed residual pressure.
- 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.
