Designed for use in refineries and other demanding environments, these durable valves have a forged steel body that can withstand at least twice the pressure of other threaded valves. They gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. All have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.

Class 800 and 1,500 valves have a flanged stem housing that you bolt in place. Unlike valves with a welded stem housing, they can be easily taken apart for maintenance and repairs.

Class 2,500 valves have a welded stem housing, which prevents leaks at the connection point. They withstand higher pressure than those with a flanged stem housing, but are not as easy to remove.

Full-port valves do not restrict flow, while standard-port valves slightly restrict flow.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Insert unthreaded pipe into the socket ends and bond with PVC primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI 61, which means they’re safe to use with drinking water systems. They gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. All have a nonrising stem that stays in the same position whether the valve is open or closed.
