Product Description
Product Description
Pressure Reducing Regulators provide a desired and constant downstream pressure, even though the upstream pressure changes. The pressure that the regulators maintain we call it setting point pressure. For the pressure-reducing regulators, the valve closes when the downstream pressure rises and opens when the downstream drops.
Features:
1. The valve body is equipped with a pressure balance mechanism, which is composed of the following parts:
Size 1/2"~5" is composed of metal bellows and a balance spring
Size 6"~16" is composed of a balanced diaphragm and balance spring
2. The valve body part and the actuator are connected together by the lock nut, which is convenient to disassemble and assemble
3. Four types of actuators can meet the requirements of different working conditions
Benefits:
1. High-precision adjustment through a pressure balance mechanism
2. Adopting modular design, different control modes can be realized by replacing the actuator
