The Series RVTX is an angle-pattern high-flow capacity 3" NPT Relief Valve, for corrosive and ultra-pure liquids. It is constructed of Grade 1, Type 1 PVC with a choice of FKM or EPDM elastomeric seals. Because of the many functions this valve performs, it is also known as a back pressure regulator and bypass valve.
The sensing element is a solid PVC shaft (or stem) with a PTFE thrust washer to reduce friction; working in conjunction with a large area rolling diaphragm. This feature enables the valve to open more rapidly, providing greater flow and sensitivity to changing pressure. Control is provided by a stainless steel spring, which is not in contact with liquid. The valve adjusting bolt and lock nut are high density polyethylene (HDPE). External fasteners are stainless steel.
Relief/back pressure setting is infinitely adjustable from 5 to 100 psi. When pressure drops below the set point, the valve automatically reseats with a bubble-tight seal. Maximum flow rate is 200 gallons per minute. Designed for heavy duty industrial use, the RVTX is ideal for acids, salt solutions, and other highly corrosive liquids. The design can be customized or made in other materials for special needs.
Part number for PVC with FKM Seals is RVTX300V-PV.
For EPDM seals, use part number RVTX300EP-PV.
