Globe Control Valve is composed of valve body, bonnet and bracket, valve stem, valve disc, valve seat, seal, inverted seal, valve stem nut, stuffing box, packing, packing gland, lock nut, hand wheel, bolt, nut And other important parts.

The flow direction of the shut-off valve is unidirectional, and it moves from left to right and from bottom to top. For a single clapper seal, there will be a small diameter reduction at the clapper seal port, which is slightly smaller than the actual flow.

The switch of the Globe Control Valve is a multi-turn rotary switch. The handwheel has impact type and ordinary switch type. Generally, the impact type is designed for large-diameter or high-pressure globe valves. The ordinary low pressure uses the stem to rise and fall together with the hand wheel.

Generally, small-diameter globe valves are connected by external threads, internal threads, ferrules, welding, etc., the general diameter is between DN5-DN25, mainly used in finely divided pipelines, such as needle-type cut-off valve. The slightly larger ones are mainly flanged. Of course, welding is also very common. For example, the high-temperature and high-pressure high-temperature and high-pressure resistant shut-off valve of power plant or special shut-off valve for power station must be used. The ammonia gas or petroleum liquefied gas pipeline should select the special shut-off valve for petroleum liquefied gas. If corrosion resistance and clean performance are required, stainless steel globe valves should be selected. If it is corrosive and the temperature and pressure are not high, you can also choose fluorine-lined globe control valve or plastic globe valve.
