Press Fittings Globe Valve

Features:

(1) The structure is simpler than the gate valve, and the manufacture and maintenance are more convenient.

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

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

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

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

(6) Medium flow direction nominal pressure PN≤16MPa, the general use of down-flow, medium from the valve disc under the direction of the upper flow; Nominal pressure PN≥20MPa, the general use of adverse current, medium from the direction of the disc down. To increase the sealing capacity. When used, the globe valve medium can only flow in a single direction, can not change the direction of flow.
