Pressure Regulation

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.

Features
• 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

* “T” in model number refers to PTFE diaphragm, FKM available, change “T” to “V”, prices are the same.

Plast-O-Matic Chemical Gauge Guards should be utilized to isolate and protect pressure or vacuum instruments used on ultra-pure or highly corrosive fluid lines. Utilization of Plast-O-Matic gauge guards offers the added advantage of protection against clogging of instruments caused by suspended solids or highly viscous fluids. Gauge Guards are available with or without gauges.

GGS-Series Gauge Guard with 2-1/2" Stainless Steel Gauges (1/4" gauge connection, 1/2" FNPT process connection)

Series RVDM In-Line Pressure Relief Valves feature a primary rolling diaphragm and secondary flat diaphragm which incorporates the Plast-O-Matic patented Fail-Dry® design for added protection. If the rolling diaphragm should fail, liquid will weep through the vent port which is located between the two diaphragms. Leakage indicates maintenance is required and can be conveniently scheduled, eliminating an emergency shutdown.  Series RVDM valves are supplied with adjustment screws so that the user can make his own setting according to pressure requirements. Pressure settings can also be made at the factory to customer’s requirements. RVDM valves can be set from 5 to 100 psi (5 to 120 psi for 1/2" size) by simply turning the adjusting bolt.
