price: contact company for price

Specification: T1- FM- TY- E

Product name : Two- stage relief valve

Model description: 316 material regulator, 6000psi( 413. bar) , Cv0.06, 1.9kg.


1. Used for making sure the precise outlet pressure although the changing range of inlet pressure is very large.

2. Setting in advance and reducing the inlet pressure to 0- 500psig( 34.4bar) when leaving factory, then get the outlet pressure required accurately through regulating hand shank.

3. Decreasing the effect to pressure supply effect because the gas in the cylinder is used up and inlet pressure fluctuate at the greatest extent.

4. Diaphragm of metal to metal is seal.

5. Excellent and stable output pressure.

6. The influence of pressure fluctuation is about 0.01% .

7. Equipped with 20 um filter in the import.

8. Max inlet pressure: 6000psi( 413. bar) .

9. Outlet pressure range: 0 to 500psi( 34.4bar) .

10. Discharge coefficient: ( Cv) 0.20( first grade) 0.06 0.20( second grade)

11. Weight: 1.9kg.
