A typical application of a seat tight proportional flow control valve is the lowering and holding of loads such as those used in a forklift truck. The pressure compensator integrated in the valve compensates for any load changes, while the volume flow and thus the traverse speed of the hydraulic cylinder can be controlled very precisely and sensitively via the solenoid current. In the deenergised…

If there is a lack of electrical power or waste heat can become a problem

The solenoid operated poppet valve with the designation SLYPM22 is characterised by a flameproof encapsulated explosion-protected solenoid coil and efficient switching behaviour. With an electrical power of just 6W, volume flows of up to 10 l/min at 350 bar can be switched. In addition, the holding power can be reduced to…

The existing proportional flow control valve is extended with the variant of a normally open function. With the normally open valve characteristic, the controlled volume flow is reduced with increasing solenoid current, while the normally closed variant increases the volume flow with increasing solenoid current. The proportional flow control valve is suitable for precise feed control systems,…

Wandfluh has extended the manually actuated throttle valve with an execution for use in very corrosive environments. The valve is made of stainless materials and coated with high-quality surface protection. It can control volume flows up to 25 l/min and the maximum operating pressure is 350 bar. The three different flow range allow the resolution of the setting to be adapted to the needs of the…
