Gate Valve 150# / 300# / 600# Class Outside Screw & Yoke Type Bolted Bonnet

The Gate Valve 150# / 300# / 600# Class Outside Screw & Yoke Type Bolted Bonnet is a heavy-duty industrial valve engineered for efficient on-off flow control in medium and high-pressure applications. Designed to provide full bore flow with minimal pressure drop, the valve is ideal for systems where complete isolation and unrestricted fluid movement are essential. Its robust construction ensures long-lasting reliability and dependable performance in demanding operating conditions.

The valve features an Outside Screw & Yoke (OS&Y) mechanism that offers clear visual indication of valve position and keeps the stem threads outside the process media, reducing corrosion and improving operational safety. The bolted bonnet design enhances structural integrity and allows convenient maintenance, inspection, and replacement of internal components without affecting pipeline alignment.

Manufactured using high-grade materials and precision-engineered components, the valve delivers excellent resistance to pressure, temperature, and wear. The non-rising handwheel operation combined with the rising stem mechanism ensures smooth opening and closing performance with secure shut-off capability. Its durable seating arrangement minimizes leakage and supports long-term operational efficiency.

Widely used in industries such as oil & gas, petrochemicals, refineries, power generation, chemical processing, marine, and water treatment plants, the Gate Valve 150# / 300# / 600# Class Outside Screw & Yoke Type Bolted Bonnet is suitable for handling water, steam, oil, gas, and various industrial fluids. It is an ideal solution for applications requiring reliable isolation, low maintenance, and consistent high-pressure performance.
