Product application:

All-Copper Flange Gate Valve BZ45W-16T

Widely used in petroleum, chemical, pharmaceutical, and power industries for opening and closing pipelines carrying steam, water, and oil media with a nominal pressure ≤1.0MPa.

Product features:

Low flow resistance. The medium channel inside the valve body is straight, allowing linear flow with minimal resistance. (2) Easy to open and close. Compared to globe valves, the gate moves perpendicular to the flow direction, making operation easier.

Large height and long opening/closing time. The gate has a long travel distance and is operated via a screw mechanism.

Less prone to water hammer. This is due to the slow closing process.

Bidirectional flow capability and easy installation. The gate valve channel is symmetrical on both sides.

Short structural length (distance between two connecting end faces of the valve body).

Sealing surfaces are prone to wear, affecting service life. During operation, the gate and seat sealing surfaces slide against each other, which can cause abrasion under medium pressure, compromising sealing performance and shortening lifespan.

Relatively expensive. Multiple sealing surfaces require complex machining, especially on the gate seat, and the valve has many components.

Simple design, short structural length, good manufacturability, and wide applicability. Compact structure, high rigidity, smooth flow channel, low flow resistance. Sealing surfaces use stainless steel and hard alloy for long service life. PTFE packing ensures reliable sealing and easy, flexible operation.
