Lalmek Hydraulics’ unique and proven pressure reversing directional control valves automatically create a forward and return movement without electrical components and thus replaces end-position switches and pressure switches. The valves feature an integrated pressure relief function that protects the hydraulic system against overpressure.

DSB3 and DS5B are directional valves with self-reversing spool hydraulic actuated, for subplate mounting. These valves reverse the flow direction when the flowrate stops in A or B line (f.e., when a cylinder reaches the end stroke). The reversing process is …

Self-reversing valve - TheHDR valves are directional control valves hydraulic actuated, with self-reversing spool. Operating pressure up to 350 bar 50l/min (HDR3), 320bar 60 l/min (HDR5)

DSB3 and DS5B are hydraulically operated self-reversing directional valves, for plate mounting. These valves reverse the direction of flow when the flow in one of the two consumers is zero (for example, when a cylinder reaches the end of its stroke). The reversal process is independent of the pressure in the consumer.

The Summit Hydraulics Hydraulic In-Line Adjustable Variable Flow Control Valve w/ Free Reverse Flow, 1/4″ SAE works great on any hydraulic system. The valve is used to provide flow control and shut-off in one direction with free reverse flow in the opposite direction.

The different reversing functions of hydraulic solenoid-operated reversing valves are realized by different spool designs. The correct spool function should be selected according to the working requirements of the hydraulic system.

2021年5月12日 · 1. Hydraulic reversing valve. This is the Directional Control Valve mainly provided by HANJIU. The hydraulic reversing valve is based on the control oil acting on the valve core, and when the control oil is under pressure, the …

sequence valves Fluid: best use mineral oil with viscosity ranging between 10 and 200 cSt. Filter: dirty oil is the main reason for failure and troubles of hydraulic parts and systems.

Pilot Operated Sequence Valve with Reverse Flow Check. For additional information see Technical Tips on pages PC1-PC6. High flow capacity. All parts steel. All operating parts hardened steel. Operating Temp. Range/Seals. NOTE: Drain line …

The valve automatically reciprocates when connected to a hydraulic cylinder, for example. When the cylinder reaches the end of its stroke, or when the load pressure rises to the relief valve setting, there is no longer any flow through the valve. …
