One-way valve is the fluid can only flow along the water inlet, but the outlet medium can't return. The throttle valve is a valve that controls the flow of fluid by changing the throttle section or throttle length. The superposition combination of the throttle valve and the check valve in parallel is the superposition check valve.


The throttle valve and the one-way throttle valve are simple flow control valves. In the hydraulic system of the fixed pump, the throttle valve and the overflow valve can be combined to form three throttle speed control systems, that is, the oil inlet throttle speed control system System, oil return line throttle speed control system and bypass throttle speed control system.


There are two types of check valves: straight-through and right-angle. The straight-through check valve is installed on the pipeline with a threaded connection. Right-angle check valves have three forms: threaded connection, plate connection and flange connection.


Main Features:

-Direct solenoid actuated directional spool valve high performance version
-Wet pin DC or AC solenoids with removable coil
