Key Features

Delivers maximum torque and rapid, fail-safe flow control in a space-saving wafer design, perfect for heavy-duty industrial pipelines.

✅Compact & Lightweight Wafer Design: Designed to fit seamlessly between standard pipe flanges, the wafer body minimizes face-to-face dimensions. This significantly reduces overall pipeline weight, footprint, and installation costs compared to traditional flanged valves.

✅High-Torque Hydraulic Actuation: Equipped with a robust hydraulic cylinder, the valve provides powerful and smooth operation. It effortlessly overcomes high dynamic fluid pressure, ensuring rapid and precise shutoff or throttling in large-diameter systems.

✅Zero-Leakage Bi-Directional Seal: Precision-engineered seating (available in EPDM, NBR, PTFE, or metal-to-metal) guarantees bubble-tight shutoff in both flow directions. It minimizes pressure drop and meets stringent international standards for industrial safety.

✅Built for Harsh Environments: Manufactured with heavy-duty, corrosion-resistant materials, this valve ensures long service life and minimal maintenance, even in the most demanding applications such as chemical processing, power generation, and marine engineering.

Structural features Technical Parameters Drawing

✅The gear and rack transmission structure is simple, reliable, compact, and provides high output torque.

✅The hydraulic cylinder is made of cast carbon steel, offering excellent overall mechanical properties and an attractive appearance.

✅The hydraulic actuator piston features an integrated structure that can withstand higher pressures and deliver greater output torque.

✅A manual operating mechanism can be installed at the bottom of the hydraulic cylinder.

✅Fine-tuning of the open and closed positions within ±5 degrees is achieved via adjusting bolts.

✅Limit switches, travel switches, and proximity switches can be installed at the top for remote control operation.

✅The bottom connection conforms to ISO5211 standards, ensuring strong versatility and easy compatibility with various valves.
✅Hydraulic Source Pressure: 2.0-16MPa

✅Ambient Temperature: -20-80°C, Low Temperature Type: -40-80°C, High Temperature Type: -20-120°C

✅Hydraulic Oil: Hydraulic oil with a viscosity not exceeding 40 CST. Low-temperature hydraulic oil should be used in low-temperature areas.

✅Installation: The installation environment should avoid outdoor, high-temperature, low-temperature, humid, and corrosive locations as much as possible. Otherwise, appropriate protection should be provided.
