Filterchem Pressure Regulators sense downstream pressure in fluid lines and open or close to maintain a selected downstream pressure. These valves are used to protect equipment and filters from excessive line pressures. These valves are adjustable from a range of 5 to 70 psi (5 to 75 psi for 1/2" size). Filterchem Pressure Relief Valves protect equipment from excess pressures by opening up at a selected pressure and relieving liquid line pressure back to a holding tank or drain. These valves are adjustable from 10 to 80 psi. Filterchem Pressure Regulators and Relief Valves are of molded construction of Type 1 PVC, with Viton® o-rings and PVDF-coated springs. Regulators are also available in polypropylene, and the pressure relief valve is also available in PVDF Kynar®.

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.
The Penguin plastic gauge guard is a unique, compact, molded design consisting of two threaded fluid chambers. There is no possibility of leakage due to uneven screwed components. Each piece contains a matching groove which confines the true o-ring incorporated on the OD of the impermeable diaphragm. A bleed plug and o-ring are included in the design for proper filling or the incompressible liquid in the gauge side chamber. This prevents air entrapment, thus providing an accurate reading with no needle vibrations.
• Choice of materials CPVC, PVDF or Polypropylene • Impermeable and resilient Viton diaphragm • 1/4" FPT instrument (gauge) connection • 1/2" FPT bottom system connection • No metallic fasteners to corrode
Advantages of Plast-O-Matic Gauge Guards
• Inexpensive initial investment • Reduces instrument failures • Reduces system down time • Eliminates special alloy instruments • Maximum chemical / temperature compatibility
