Flanged Gradual On/Off Valves
With Wheel Handle,
Rising Stem, and
Eight Bolt Holes
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.
