Series SOV Shut Off Valves offer low torque, quarter turn, positive shut off of forward flow up to 3000 PSIG (207 bar). These valves feature a one-piece body construction with a machined metallic replaceable plug stem. Sealing is accomplished with a standard elastomeric O-Ring seal.
Larger size valves utilize Teflon Backup Rings to reduce operating torque and provide long service life. Available in 1/8"–1/2" Dual Ferrule Tube and NPT connections, Brass or 316 Stainless Steel. Optional Downstream Vent configuration available.
