The Type 582 Pressure Reducing Valve shall control downstream pressure. The set pressure is controlled via an adjustment screw. The spindle is of non-rising design. The bonnet connection is of threaded design. The seal material is indicated by color coded external tab. Following assembly, every valve is tested and certified bubble tight exceeding Class VI standards. The Compact design enables installation even where space is limited. Threaded bonnet eliminates the need for body assembly bolts. Significantly shorter lay length with union ends. No need to re-torque due to threaded bonnet. Easily adjusted set pressure with non-rising spindle. Constant and low vibrating control behavior. Tightness resistant to temperature cycling. Adjustment of set pressure possible during operation. Pressure gauge options for aggressive media. Connection options in true union, spigot or flanged. Low pressure spring set available (4-44 psi) Optional Pressure Gauges. Pressure gauge mounting on either side of the 582 valve to accommodate required installation direction. Standard gauges are 304 stainless steel or brass with either EPDM or FPM elastomeric seals. Valve bodies of all varieties can accommodate two pressure gauges.
Pressure Retaining Valve Type 586 are engineered for precise control in your application. Retaining and reducing valves offer superior performance with minimal space requirements. The modular design provides configuration flexibility and easily replaceable cartridges facilitate maintenance and reduce required spare parts. Pressure regulating valves with a completely re-engineered design. The new valves are compact - without restricting performance in any way. They are easy to install and operate - the set screw controls a non-rising spindle for even flow control. The PRV’s are flexible due to the modular design, allowing part interchange between multiple sizes of valves and components. 586 pressure valves are available in PVC, CPVC, Polypropylene, and PVDF. Diaphragm is PTFE/EPDM. Seals can be EPDM, FPM or PTFE. Bonnet assembly is glass-filled polypropylene. The 582 Pressure Reducing Valve reduces the line pressure to a set value on the valve outlet. The outlet pressure is in no direct relation to the inlet pressure. Independent of rising or falling inlet pressure, the outlet pressure stays constant. The 586 Pressure Retaining Valve maintains the line pressure to a set value on the valve inlet. The inlet pressure is in direct relation to the flow. Independent of pressure fluctuations., the system pressure stays largely constant. The Type 586 can be used in relief applications in combination with a tee.
