1、 Gas ball valve — Product Overview:
Aiming at the disadvantages of common cast steel valve with poor corrosion resistance and easy perforation of shell, according to the specific characteristics of medium, corrosion-resistant steel (carbon steel added with corrosion-resistant alloy element) is selected for the valve body material of ammonia special ball valve, which can resist the corrosion of gas and liquid ammonia, and the low temperature can be as low as – 40 ℃ – 120 ℃. It can meet the requirements of working conditions to the maximum extent. It is widely used in petroleum, chemical, pharmaceutical, chemical fertilizer and other industries.
2、 Special gas ball valve sealing advantages:
The main valve seat sealing ring material of gas ball valve is PTFE, which is inert to almost all chemical substances, and has the comprehensive characteristics of small friction coefficient, stable performance, no aging, wide temperature range and good sealing performance.
3、 Gas ball valves – Performance Specifications:
Nominal pressure PN (MPA): 1.6-4.0
Test pressure PS (MPA): 2.4-6.4
Applicable medium: ammonia, liquid ammonia and gas
Applicable temperature (℃): 40 ℃ 80 ℃
