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

(1)shell Hydrostatic Test

ANSI B 16.34 Section 7.1
Valve Size NPS	Test Pressure	Test Time.Sce
DN50 below	1:5 times zhe100° F	15 seconds
DN65~DN200	Rating of ANSI Class	60 seconds
DN250 above	Max.Operating Pressure	180 seconds
	Check the pressure to more than 1.5 times higher than the maximum pressure valve

(2)Seal Hydrostatic Test

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

ANSI B 16.34 Section 7.2
Valve Size NPS	Test Pressure	Test Time.Sce
DN50 below	1:5 times zhe100° F	15 seconds
DN65~DN200	Rating of ANSI Class	30 seconds
DN250 above	Max.Operating Pressure	60 seconds
	Check the pressure to more than 1.5 times higher than the maximum pressure valve (100 f)	120 seconds

(3)Seal Air Test

Seal air leakage test is based on 80PSIG(6kgf/cm2)nin-actiue gas of full lilled with air, after clase zhe valve.then check it is leakage or not by one side of zhe valve
