Globe Valve

Zeco produces cast globe valves and forged globe valve , two categories of globe are specially designed for the corresponding operating conditions, almost covering the operating conditions of various water and industrial systems. Globe valve, also known as the cut-off valve, is one of the most widely used valves. It is popular because of the small friction between the sealing surface in the process of opening and closing, relatively durable, small opening height, easy to manufacture, easy to maintain, not only suitable for low pressure, but also suitable for high pressure. The closing principle of the globe valve is to make the sealing surface of the valve disc closely fit the sealing surface of the valve seat by relying on the pressure of the valve bar to prevent media circulation.The flow direction of my globe valve is from top to bottom.The structure of the globe valve is longer than the gate valve, at the same time the fluid resistance is large, long-term operation, sealing reliability is not strong. Zeco globe valve, as one of the most important truncation valves, plays an important role in the field of aerospace.As an important component of space equipment, the cut-off valve realizes the functions of medium transportation, cut-off and adjustment, and its sealing performance directly affects the safe and reliable operation of space equipment.The study on the influencing factors and influencing rules of typical globe valve sealing characteristics is of guiding significance to the structural design of valve sealing pair, so as to improve the sealing performance and reliability of valve.
