About Gradual On/Off Valves

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. Their flanged stem housing bolts in place and makes them easy to take apart for maintenance and repairs.

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.

Flanged Gradual On/Off Valves

With Wheel Handle,
Rising Stem, and
Eight Bolt Holes

Bolt these valves to flanges. They gradually open and close to prevent system damage from suddenly starting and stopping flow.

Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than pull handles.

Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.

High-Pressure Socket-Connect Gradual On/Off Valves

Valve Type: Gate
For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Xenon, Steam
Specifications Met: American Petroleum Institute Standard 602, ASTM A105N

With a forged steel body and bolted construction that can withstand at least twice the pressure of other socket-connect valves, these are often used in refineries and other demanding environments. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. 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.

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.
