This bellows type pressure reducing valve is mainly composed of bellow pipe, adjusting springs, valve seat, valve disc, and other components. It uses bellow pipe to sense the pressure of the valve and drive the valve disc, changing and controlling the valve opening angle to achieve pressure reduction and pressure stabilization. This valve is a direct acting type, which using bellow pipe as sensitive components to automatically change the opening of the valve disc using the predetermined setting of the adjusting spring, so as to reduce the inlet pressure to a desired outlet pressure, When the inlet pressure and outlet flow rate change within a certain range, it can use its own energy to automatically maintain the outlet pressure within a certain range.

1. Small size and light weight.

2. The pressure detection device uses bellow pipe with good durability.

3. By rotating the plastic hand-wheel, the pressure can be adjusted without the need for tools, making it easy to operate (counterclockwise rotation increases the pressure; clockwise rotation reduces the pressure)

4. Equipped with a filter screen inside, it can protect the valve performance from dust and impurities

5. Adopting internal thread connection for easy installation

6. The valve body and valve seat are made of stainless steel material, with a long service life.
