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.

Series RVDT In-Line Pressure Relief Valves feature a wetted flat PTFE diaphragm to resist both chemical attack and salt crystallization problems. A large, active diaphragm area provides for smooth, chatter-free operation. Relief setting is infinitely adjustable from 5 PSI to 100 PSI. This design functions as a relief valve, by-pass valve, back-pressure valve and anti-siphon valve. The Relief Function protects systems and equipment from over-pressure and pressure surges. The By-Pass Function prevents pumps from “dead-heading”. The Back- Pressure Function maintains necessary reverse pressure in closed-loop systems. The Anti- Siphon Function prevents unwanted chemical siphoning, if city water pressure drops to zero, and changes in elevation create negative pressure. Series RVDT relief valves are constructed of Type 1, Grade 1 PVC, CPVC, Polypropylene, PTFE or PVDF Kynar® body materials. The wetted diaphragm is PTFE, energized by a non-wetted Viton® diaphragm. Springs (not in wetted area) are zinc-plated steel, fasteners are stainless steel and the adjusting screw is polyethylene.
