MISSION

API 600 gate valve

Gate valves are primarily designed for on-off services. They are best used in systems which require infrequent use of the valve. The valves are designed for full-area flow to minimize the pressure drop and allow the passage of a pipe-cleaning pig. Since most of the flow change occurs near the shutoff, the relatively high fluid velocity causes disk and seat wear and eventual leakage if the valve is used to regulate flow.

Features

Valve body and valve cover may be connected by bolts or pressure self-tight

The sealing principle of wedge gate valve is seal through close connection of wedging of two sealing faces of wedge flashboard and two sealing faces of valve body.

The flashboard has two sealing faces. The most commonly used flashboard has a wedge forming by two sealing faces. The wedge angle varies with valve parameters, usually 5°.

Wedge gate valve may be divided into outside stem gate valve (rising stem gate valve) and inside stem gate valve (revolving stem gate valve) according to different opening and closing modes of flashboard driven by valve stem.
