Product details

Natural gas flat gate valve is specifically designed for natural gas, liquid petroleum gas, coal gas, oil products, etc. It completely solves the problems of valve tightness and inability to open caused by gas coking with its unique design, novel structure, and good sealing performance, effectively improving the sealing performance and service life. Truly achieving zero leakage. The valve is lightweight and durable when opened. Please add "K" before the sulfur resistant valve model, "L" before the regulating valve model, and "M" after the wear-resistant model F.
