In water supply and drainage, HVAC, and industrial gas transmission systems, the diaphragm pressure reducing valve DN50 is the first choice for many engineering projects due to its excellent low-pressure precision stable regulation capability. For purchasers, the two most critical concerns are its price and pressure regulation performance.The main pressure reducing valve product names of China Pressure Reducing Valve Network include:200P Reducing Valve,Air Filter Reductor,Branch Pipe Reducing Valve,Combined Type Reducing Valve,Corrugated Pipe Type Reducing Valve,Direct Effect-Type diaphragm Spring Reducing Valve,diaphragm Adjustable Reducing And Stabilized Valve

Factors Affecting the Price of Diaphragm Pressure Reducing Valve DN50

Currently, the price of a DN50 diaphragm pressure reducing valve generally ranges from RMB 500 to 2,800, depending on the following three factors:

Valve Body Material: Copper alloy (approx. RMB 500–900), suitable for water and air; ductile iron (approx. RMB 800–1,500); stainless steel (304/316) (approx. RMB 1,800–2,800), suitable for corrosive media.Pressure relief valveNews

Pressure Rating: Standard PN16 models are more affordable, while PN25 and above high-pressure models cost more.

Brand & Accuracy: Ordinary domestic brands offer higher cost performance, while precision stable regulation models that control outlet pressure fluctuation within ±0.02 MPa are typically 30%–50% more expensive. Pressure relief valveStandard

Core Advantages of Low-Pressure Precision Stable Regulation

This type of valve is specifically designed for low-pressure applications with inlet pressure ≤1.6 MPa and outlet pressure between 0.1–0.8 MPa. Compared with piston-type structures, the diaphragm type responds more sensitively, instantly sensing minor downstream pressure changes and automatically adjusting the opening to achieve precise pressure regulation. It is especially suitable for systems sensitive to pressure fluctuations, such as laboratory gas lines, constant-pressure water supply, and gas pipelines.Pressure relief valve Products

Purchasing and Quotation Suggestions

Clarify operating parameters: Medium (water, air, oil), temperature, and required pressure regulation accuracy.

Request actual case data: Ask suppliers for pressure regulation test results from similar models.

Pay attention to installation details: A strainer should be installed upstream of the diaphragm pressure reducing valve, and it is recommended to reserve a pressure gauge port for on-site calibration.

For an accurate current diaphragm pressure reducing valve DN50 price, it is advisable to directly consult multiple brand distributors and specifically state the requirement for "low-pressure precision stable regulation" to obtain precise quotations. Bulk purchases often leave room for negotiation.
