SUA unidirectional control valves (Gas thread) allow free oil flow in one direction and regulate the flow in the opposite direction.
Flow regulators by rotary knob
They are used when you want to regulate the oil flow in one direction and have the full flow in the opposite direction, the valves are not compensated so the setting depends on the operating pressure, viscosity and temperature of the fluid.
The range includes different threads from 1/4 BSPP ( 1/4 G ) up to 1 BSPP ( 1 G ).
In this version there is an external thread for tightening the valves with the ring nut.
Setting is made by t made by knob rotation clockwise and vice versa, to lock tighten the lateral nut placed on the knob.
The external body is made of high-resistance steel and is protected from oxidation by a zinc treatment.
It is possible to request a surface treatment in zinc/nickel to increase the resistance to oxidation, in case the valve is poorly protected and exposed to atmospheric agents.
