Product Overview

Natural gas flat gate valve adopts new floating seal structure, suitable for natural gas pipeline with high content of H2S gas, for the opening and closing of the control medium and regulating device, natural gas flat gate valve has novel structural design, proper material selection, strict testing, easy to operate, and strong anti-corrosion, wear-resistant, erosion-resistant performance, suitable for natural gas, petroleum, chemical industry, environmental protection, urban pipelines, gas pipelines and other transmission pipelines, venting systems and steam storage devices, used as opening and closing equipment. It is suitable for natural gas, petroleum, chemical, environmental protection, city pipeline, gas pipeline and other pipelines, venting system and vapor storage device, used as opening and closing equipment.

Structural Features

Natural gas flat gate valve is a kind of sliding valve with parallel gates as closing parts. The closing member can be a single gate or a double gate with a spreading mechanism. The pressure of the gate to the seat is controlled by the pressure of the medium acting on the floating gate or the floating seat. In the case of double-gate flat gate valves, this pressure is supplemented by a spreader mechanism between the two gates.


Natural gas flat plate gate valve is specialized in natural gas, liquid petroleum gas gas, oil and so on. Its unique design, novel structure and good sealing performance completely solve the valve due to gas coking caused by the closure of not tight, open and so on, effectively improve the sealing performance and service life. Zero leakage is really achieved. The valve opens light and durable, Note: anti-sulfur valve model before adding "K", regulating valve model before adding "L", wear-resistant ModelF after adding "M".
