Stainless Steel Bellows Gate Valve

Stainless Steel Bellows Gate Valve

Introduction:

When the corrugated pipe gate valve is opened, when the opening height of the valve clack is 25%~30% of the nominal diameter, the flow has reached the maximum, indicating that the valve has reached the full open position. Therefore, the full open position of the stop valve shall be determined by the stroke of the valve disc. The electric gate valve is sensitive, safe and reliable. Many plants with high control requirements set up compressed air stations for pneumatic instrument control elements. The electric one needs electricity. And can control its flow.

The types of bellows gate valves are divided into external thread type and internal thread type according to the position of the stem thread. According to the flow direction of the medium, there are straight through type, direct current type and angle type. The stop valves are divided into packing bellows gate valves and bellows seal stop valves according to the sealing form.

Advantage:
1. Simple structure, easy to manufacture and maintain.
2. The working stroke is small and the opening and closing time is short.
3. Good sealing performance, low friction between sealing surfaces, long service life.

The disadvantages of bellows gate valves are as follows:
1. The fluid resistance is large, and the force required for opening and closing is large.
2. It is not applicable to medium with particles, high viscosity and easy coking.
3. Poor regulation performance.
