The valve is equipped with synthetic rubber, ensuring good stopping performance when the valve is closed!
The PPD41B-3 type (for gas) is a pressure reducing valve that employs a secondary pressure balance system in the valve body, which means that the secondary side pressure is hardly affected by fluctuations in the primary measurement pressure. The valve body is equipped with synthetic rubber, ensuring good sealing when the valve is closed. In the case of bronze (for 1.6 MPa) and stainless steel castings for the valve box, a strainer is built-in. We can also manufacture high-pressure gas equipment certified products (valve box: stainless steel). 【Features】 ■ Adopts a secondary pressure balance system in the valve body ■ The secondary side pressure is hardly affected by fluctuations in the primary measurement pressure ■ Equipped with synthetic rubber in the valve body, ensuring good sealing when the valve is closed ■ Built-in strainer for valve box materials of bronze (for 1.6 MPa) and stainless steel castings ■ Capable of manufacturing high-pressure gas equipment certified products (valve box: stainless steel) *For more details, please refer to the PDF document or feel free to contact us.
