Valves & Actuation

This full-featured valve is engineered to provide accurate throttling control and shut-off for industrial, chemical and water treatment applications, as well as the handling of liquids with suspended solids, viscous fluids and slurries. Weir-type design utilizes a choice of elastomeric diaphragms with non-rising stem and built-in position indicator. Strong buttress thread, true union style end connection allows ease of installation and service. Available in IPS sizes 1/2” through 2” with socket and threaded end connectors. Heavy-bodied Schedule 80 PVC or CPVC smooth-wall construction provides extra strength, superior chemical and corrosion resistance while maximizing fluid flow. Choice of high-grade, abrasion-resistant EPDM, Viton® or elastomer-backed PTFE-laminated diaphragm allows application specific selection for optimum chemical resistance.
Features
• 235 psi @ 73°F (for complete size range)  • Built-in mounting holes for self-tapping screws  • Rugged construction with strong buttress threads  • Available with EPDM, Viton® or PTFE diaphragm  • Dual end connectors (socket and thread) on PVC and CPVC  • SR threaded ends - SS-reinforced threaded end connectors
