Product Overview

Gate valves are used as shut-off media, and when fully opened, the entire flow is straight through, resulting in minimal pressure loss during the operation of the medium. Gate valves are usually suitable for working conditions that do not require frequent opening and closing, and keep the gate fully open or closed. Not suitable for use as a regulator or throttle. For high-speed flowing media, the gate may vibrate when partially opened, which may in turn damage the gate. Wedge gate valves are widely used as opening and closing devices for connecting or cutting off media in oil and steam pipelines such as petrochemicals and thermal power plants. They are generally used in situations where the external dimensions of the valve are not strictly required and the usage conditions are relatively harsh.

Structural Features

Wedge gate valve product features: 1. Compact structure, reasonable design, good valve rigidity, smooth channel, small flow coefficient. 2. Stainless steel and hard alloy sealing surface are used for long service life. 3. Flexible graphite packing is used for reliable sealing and easy and flexible operation. 4. The driving mode is manual, pneumatic, electric, and gear transmission. 5. The structural form is elastic wedge single gate, rigid wedge single gate, and double gate.
