The RVDT series is a line of PTFE diaphragm relief, by-pass, anti-siphon, and backpressure valves for pressure control in industrial systems. Valves are available in PVC, CPVC, polypropylene, Kynar PVDF, PTFE, and 316L stainless steel bodies with sizes from 1/4" to 4". Relief settings are infinitely adjustable from 5 psi to 125 psi, with maximum inlet pressure rated at 150 psi at 75°F. The PTFE diaphragm ensures contamination-free sealing for corrosive and ultra-pure fluids. Mounting includes integral lugs on 1/2" and 1" thermoplastic models, and threaded holes elsewhere. 1/4" to 3" sizes in PVC, CPVC, and stainless steel are NSF/ANSI 61 and NSF/ANSI 372 certified. Flow rates and physical dimensions vary by size and material, with 3" and 4" models featuring heavy-duty hand-fabricated construction. All valves are individually pressure-tested prior to shipment.
Series RVDT/RVDTM is a universal automatic backpressure control valve for pressure relief, pump backpressure, pump bypass, anti-siphon, and backpressure regulator applications. Thermoplastic or Metal Valves designed for smooth, sensitive operation and the ultimate in corrosion resistance or ultrapure liquid handling with no wetted elastomers. Upstream pressure settings to 125 PSI on most models.
Available in Geon PVC and Corzan CPVC body materials in 1/4″- 3″ sizes; Natural Polypropylene and Kynar PVDF body materials in 1/4″ – 2″ sizes; PTFE body material in 1/4″ – 1″ sizes; Stainless Steel body in 1/2″ – 1″. A complete range of connection types available.
