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.

This series of products are reliable sealing performance, maintenance-free for 20 years, switch torque light,can be installed in heat transfer stations, district heating pipe network, branch pipes, heat exchanger unit, heat transfer equipment or ancillary equipment connected to other.use for cut off . The main use of the urban heat, city gas, city water supply and drainage lines.

Full bore lever type: gas heat & water used fully welded ball valve (DN15~150)

CERTIFICATION: ISO, TS, API, GOST, CE....etc

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

ANSI B 16.34 Section 7.2
Valve Size NPS	Test pressure	Test Time. Sce
below DN50	1:1 times the 100°F	15 Sce
DN65~DN200	Rating of ANSI Class	30 Sce
above DN250	Max. Operating Pressure	60 Sce
	Test pressure should be more 1.5 times than the valve's Max work pressure (100F)	180Sce

(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.
