JC4330 Zero Pressure Controller
■ Zero pressure controller to overcome the current market pressure controller commonly exists to reduce the pressure to zero level to return to the phenomenon of not working.
■ The zero pressure controller is especially adapted to the system low pressure alarm.
■ The zero pressure controller uses diaphragm (imported) sensors for air, gas and water, steam, hydraulic oil, light fuel oil and other liquid media. (If the customer uses it for corrosive gases or liquids, please specify in the order request.)
