A hydraulic power unit (HPU) configured for use with a pressure relief valve (PRV) having an open port and a close port is provided. The HPU includes a pneumatic primary pump, a hydraulic fluid reservoir, an accumulator, and a two position solenoid directional valve (TPSDV). The hydraulic...
Set pressure control— Valve operation method Constant (default) | Controlled Opening parameterization— Method of modeling constant valve opening or closing Linear - Area vs. pressure (default) | Tabulated data - Area vs. pressure | Tabulated data - Volumetric flow rate vs. pressure Opening pressur...
◆The pressure reducing valve is a very easy operation of the pressure control valve which provides precise control and easy installation and maintenance. ◆The valve can control the valve after pressure without the need for a pneumatic or electric control element.Pressure relief valve is a two-se...
The 50 Series Pressure Relief Valve is designed to maintain constant upstream pressure within close limits. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. In addition to surg...
When the medium is steam, the pilot piston type or the pilot bellows type pressure reducing valve should be selected; For the convenience of operation, adjustment and maintenance, the pressure reducing valve should generally be installed on the horizontal pipeline.Pneumatic...
