The German Lake brand imported self-operated (behind the valve) pressure control valve consists of a control valve, an actuator and a spring for setting the pressure. It is suitable for non-corrosive liquids, gases and steam. It plays the role of pressure control behind the valve in the system pipeline. When the pressure behind the valve rises, the control valve closes.
