Product details

The stem axis of the fillet globe valve is perpendicular to the sealing surface of the valve seat. The stem opening or closing stroke is relatively short and has a very reliable cutting-off action, making this valve ideal for use as a medium cut-off or regulation and throttling.

Once the valve is in the open position, there is no further contact between the sealing surfaces of the valve seat and the valve flap, which results in less mechanical wear on the sealing surfaces. The direction of flow of the medium through these valves changes, so the flow resistance of the globe valve is higher than that of other valves. This type of valve in the pipeline should generally be installed horizontally.

Features of the threaded globe valve:

(1) Structure than the gate valve is simple, manufacturing and maintenance are more convenient.

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

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

(4) Opening and closing torque, opening and closing more laborious, opening and closing time headmaster.

(5) Fluid resistance, because the valve body media channel is more tortuous, fluid resistance, power consumption.

(6) Media flow direction Nominal pressure PN ≤ 16MPa, generally used in the downstream, the media from the direction of upward flow under the valve flap; nominal pressure PN ≥ 20MPa, the general use of counterflow, the media from the valve flap downward flow.

To increase the seal energy. When using, the globe valve media can only flow in one direction, can not change the direction of flow.

(7) Fully open when the valve flap is often eroded.

Product advantages:

(1) The ball valve has a simple structure, small volume, light weight, small flow resistance and good energy-saving effect. When the medium flows through the gate valve, it is equivalent to flowing through a straight pipeline, in all kinds of valves, the gate valve has the smallest fluid resistance.

(2) Fluid into, out of the valve direction can be arbitrarily selected, with two-way role.

(3) Horizontal pipeline, vertical pipeline can be installed.

(4) Easy to operate, quick to open and close, hand turn the hand wheel a few turns to achieve the switch.

(5) The valve has good anti-leakage effect and long service life.
