Slide valve WRV series
برند:
Universal Hydraulik GmbH
مشخصات:
onsists of an adjustment part, a valve, and a thermostatic element. The spring housing of the adjustment part is provided with a neutral scale reading from 1 to 5. The valve housing has an internal thread to provide a connection facility for pipes. Sealing of the valve spindle is achieved with the help of rubber diaphragms which, at the same time, ensure that the valve operates almost independent from pressure ratios. The spindle is located in slide bushes with O-rings. These O-rings are located outside the diaphragms and ensure additional safety and sealing. Thanks to the symmetric construction of the valve housing, the valve can operate as either an opening valve (WRV-O) or closing valve (WRV-S). Any change in the operation of WRV-O or WRV-S valves is achieved by turning the valve housing, so that the identification marking “1/2 DA” is pointing to the upper part. The thermostatic element consists of a corrugated pipe, capillary tube, and sensor.
