Hydraulic Bidirectional Normally Open Solenoid Valve

Hydraulic Bidirectional Normally Open Solenoid Valve

Longli`s 2-way bi-directional poppet solenoid valves feature a proven design that ensures very low leakage when in the double-blocking position and minimized pressure drop in the free flow position. These valves can operate with hydraulic system flows as high as 285 lpm and pressures up to 350 bar with normally-open or normally closed configurations available. Some of Longli`s 2-way bi-directional poppet solenoid valves contain built-in thermal reliefs set at 36 bar, but all are ideal for unloading and load holding applications that require low poppet style leakage within mobile, industrial, or manufacturing markets. 

Longli`s 2 way poppet valves are pilot operated, low leakage solenoid actuated valves. Similar to a check valve, these valves will block flow in one direction will very low leakage (5 drops per minute, or less). When actuated, these valves allow flow to pass through the valve. These valves are typically selected due to their low leakage characteristics and their ability to meet higher flow requirements. Poppet valves are often used on single operation actuators or in unloading functions. They are available in normally closed and normally open types with fast response versions available. 
Longli`s two way, two position poppet valves consist of a main poppet, a pilot piston, a spring, and a solenoid coil. 
The normally open poppet version of these valves, when the coil is de-energized, will allow free flow from the side port of the valve (port 2) out the nose of the valve (port 1). Energizing the coil shifts the poppet to block flow in both directions.
