1、 Product Features

V13005/ZA3 self operated flow and pressure combination valve

V13005/ZA3 self operated flow and pressure combination valveSelf operated flow pressure combination valveIt is an energy-saving multi combination control valve that does not require external energy. It is used as a control device for non corrosive water and other liquid media with a maximum temperature of 200 ℃, flow rate, and pressure. The flow valve is combined with the ZA3 type actuator through a combination control valve.

Principle of Action

When flow and pressure are combined for control, the valve operates sequentially according to the different input sequences of the flow valve and pressure valve (behind the valve). When either the flow rate or pressure (behind the valve) reaches or exceeds the set value, the valve will operate according to its requirements to meet various control requirements on site.
