Quick Release Couplings – Straight Through 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-STV (Straight through Valve) This is a double path open type coupler which does not have a valve mechanism at either the socket nor the plug. It is used in piping systems in which blocking of the fluid when disconnected is unnecessary and closure of lines is achieved by back up valves. Permit full flow capability due to their smith and accurately finished bores.
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.
Specifications:
1. Used for pneumatic systems.
2. Working pressure: Less than 145 Psi; Max pressure: 150 PSI.
3. Material: Brass and steel are both available.
4. Temperature range: -20~70 Celsius Degree.
5. Air flow: 35 SCFM at 100 PSIG inlet with10 PSIG pressure.
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:
- 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.
- 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.
