Valves — API SPEC 6A COMPLIANT

---

The manual gate valve features an internal gate positioned perpendicular (90°) to the flow path. When the handwheel is turned, the stem or stem nut drives the gate vertically to open or close the flow passage, providing reliable sealing and flow control.

Engineered for simplicity and durability, this valve is ideal for applications requiring manual control of fluid flow in pipelines or wellhead systems.

The hydraulic gate valve features an internal gate positioned at a 90° angle to the flow path, ensuring dependable flow isolation. Equipped with a bidirectional hydraulic actuator, the valve operates by directing hydraulic fluid into the actuator, where the piston drives the stem and gate vertically to open or close the flow passage.

This design enables precise remote control, reliable sealing, and efficient operation—ideal for high-pressure oil and gas applications where automation and safety are paramount.

The Surface Safety Valve (SSV) is a critical safety component designed to provide rapid shutoff in emergency situations. Internally, the valve features a gate positioned at a 90° angle to the flow path. It is equipped with a hydraulic or pneumatic actuator that controls valve operation.

When control pressure is applied, the actuator piston moves downward, driving the stem and gate to open the valve. Upon loss of control pressure, a spring mechanism automatically returns the valve to the closed position, ensuring fail-safe operation.

Engineered for high-reliability wellhead and flowline applications, the SSV offers quick response, robust construction, and dependable sealing to protect personnel, equipment, and the environment.

The specialized fracturing gate valve is an enhanced version of the conventional flat gate valve. 

It features a unique anti-sand design and other structural upgrades, making it well-suited for high-flow, high-pressure, and high-sand-content fracturing operations. 

The adjustable choke valve is equipped with variable flow components and can be operated manually, hydraulically, pneumatically, or electrically. Under the applied driving force, the orifice size of the flow component is adjusted to regulate and control fluid flow rate and pressure with precision. 

The fixed choke valve is equipped with replaceable choke beans of various orifice sizes. By selecting and installing the appropriate choke bean based on operational requirements, it provides reliable control over fluid flow rate and pressure. 

The check valve allows fluid to flow in one direction only, automatically preventing reverse flow. This lift-type check valve relies on fluid pressure to lift the valve disc, achieving a reliable metal-to-metal seal between the disc and valve body.
