Five Advantages:

1. integral seamless steel tube pressed full-auto welded without leaking outward.

2. PTFE+25% carbon fiber and disc spring feely compensating structure zero leakage.

3. can be directly buried without need of a high ground well,saving the engineering cost.

4. both valve and pipeling are made of the same material, without the condition of uneven sterss.

5. in multiple connection combination, for use with special working conditions.

We pay much attention in Test process:

(1) Shell Hydrostatic Test

ANSI B 16.34 Section   7.1

Valve Size NPS

Test pressure

Test Time. Sce

Below DN50

1:5 times the 100°F

15 Sce

DN65~DN200

Rating of  ANSI  Class

60 Sce

Up DN250

Max. Operating Pressure

180 Sce


Test pressure should   be above 1.5 times  than the valve's Max work pressure (100F)


(2) Seal Hydrostatic Test

The pressure should be more 1.1 times than working pressure by seal hydrastatic test

(3) Seal Air Test

Seal air leakage test is based on 80PSIG(6kgf/cm2) inert-gas or the air reach the test pressure, then close the valve. after that check the valve whether it is leakage or not.
