Zawór dławiąco-zwrotny WRFU 90 3/4"BSP Waryński

Throttle check valve WRFU 90 with internal thread 3/4"BSP Waryński. The task of throttle check valves is to affect the value of the working fluid flow supplied to the receiver. By regulating/changing the oil flow rate, you can control, for example, the working speed of hydraulic cylinders or hydraulic motors, which are powered by a hydraulic pump with a constant capacity. Throttling works only in one direction. In the opposite direction, the built-in check valve (opening at a pressure of 0.5 bar) allows unthrottled return flow. The repeatability of the setting can be checked on the scale located on the knob. The volume flow depends on the pressure difference and the viscosity of the hydraulic oil. They are designed in accordance with the dimensional and quality requirements, which specify in detail the operating characteristics and dimensions. Thanks to their strong construction, they are suitable for use in difficult working conditions in agricultural and construction machines.
