Description
These valves control the flow using an adjustable choke reducer that is not pressure compensated, so the flow is entirely dependent on the pressure drop at the setting of the given choke reducer.
Models with two service lines are equipped with a built-in check valve around each control throttle reducer, allowing for inflow or outflow control; single-line versions are also available.
For flow restriction in the P or T lines (where backflow is not required), models without a check valve are also available.
Adjustment options include screw/locking nut or handwheel.
