Jiayuan check valve is designed with compact one piece body, it is the flow control device used primarily in hydraulic systems, to eliminate potential damage caused by fluid back pressure.
Hydraulic check valve is different from non-return valve, A check valve is a very strict criteria, with dependable internal compact design, have a higher Operating Pressure Requirement.
Compact Design. Easy to plumb into tight circuits.
All steel construction. No internal gaskets or seals to wear out.
One-piece body eliminates threads and seals that may be potential leakage points.
Smooth flow stream. Poppet spring is isolated from flow stream.
Variety of end fittings.
Chromium-6 Free plated exterior finish.
Jiayuan offer check valves with metal to metal hard seat, a one piece body and all steel construction. It consists of a valve body with an inlet and an outlet port. Inside, a moveable poppet valve is controlled by spring pressure.
Check valves are important components that are often overlooked when building a fluid system. A check valve can optimize system performance in the following ways:
Ensure hydraulic fluid flows in only one direction.
Eliminate potential damage from back pressure.
Isolate sections of a system or system components.
Sizes: 1/4” to 1-1/4”
Inlet Port Ends: Male ORB, Male JIC, Male ORFS
Outlet Port Ends: Male ORB, Male JIC, Male ORFS
Custom shapes and configurations
Applications typical in hydraulic circuit, the check valve is used to protect the pump by preventing pressure from returning to the outlet port of the pump:
Industrial, mobile, and construction equipment
Restrictor Check Circuit
High/Low Pump Circuit
Slow Advance/Rapid Return Circuit
Oil Cooler By-Pass Circuit
Pilot Pressure Circuit
