Information

Stainless steel globe valve is a kind of globe valve, the body material requirements are relatively high generally 301.304.316 and other materials are widely used in chemical industry, shipping, medicine, food machinery and other industries.Stainless steel globe valves are divided into manual stainless steel globe valves, pneumatic stainless steel globe valves, electric stainless steel globe valves.

(1) Simpler structure than gate valve, more convenient manufacture and maintenance.

(2) Sealing surface is not easy to wear and scratch, good sealing, there is no relative sliding between valve disc and valve body sealing surface when opening and closing, so wear and scratch are not serious, good sealing performance, long service life.

(3) When opening and closing, the disc stroke is small, so the globe valve height is smaller than the gate valve, but the structure length is longer than the gate valve.

(4) The opening and closing moment is large, the opening and closing is more strenuous, the opening and closing time principal.

(5) High fluid resistance, because the medium channel in the valve body is tortuous, high fluid resistance, high power consumption.

(6) When the nominal pressure PN≤16MPa in the direction of medium flow, downstream flow is generally adopted. Medium flows upstream from the lower direction of the valve disc;Nominal pressure PN≥20MPa, the general use of counterflow, the medium from the direction of the disc flow.To increase the seal energy.When in use, the globe valve medium can only flow in one direction, can not change the flow direction.

(7) When fully open, the disc is often eroded.
