  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.   Packaging & Shipping   Our Services   1.100% factory price, because we are direct producer of ball valve, butterfly valves, check/non-return valves, gate valves and so on. 2.Market, technical support and after-sale service within 24 hours. 3.
