Gate valves provide an effective solution for ensuring a tight shutoff in systems where leakage could lead to operational failures or safety hazards. Their precision-seated design guarantees zero leakage, even under high-pressure conditions, minimizing the risk of fluid bypass. This feature is especially important in applications like oil and gas pipelines or chemical processing, where preventing leaks is crucial for both system integrity and environmental safety. The materials used in these valves ensure the sealing surface remains durable over time, offering a long-lasting solution for critical applications.

Valve Type

Linear motion isolation valve designed for full open or closed service in pipelines.

Flow Regulation Method

On/off control; not suitable for throttling or regulating fluid flow rates accurately.

Differential Pressure Range

Typically operates effectively under low to moderate differential pressure across the valve.

Hydraulic Authority Recommendation

Low hydraulic authority; not recommended for applications requiring precise flow control.

Valve Characteristic Curve

Exhibits a linear flow characteristic only when fully open or fully closed.

Product Description

Gate valves offer a robust solution to withstand the challenges posed by corrosive, abrasive, and high-temperature environments. With materials such as stainless steel, Hastelloy, or specialized alloys, these valves are engineered to resist corrosion and fatigue, ensuring reliable performance even in the harshest conditions. Whether used in offshore platforms, refineries, or chemical plants, gate valves are designed to perform without failure, thus reducing the need for frequent replacements and minimizing downtime in your operations.

Test Point Configuration

Standard test points not included; optional fittings available for pressure monitoring.

Maximum Allowable Flow Velocity

Maximum recommended flow velocity is 5 m/s to prevent erosion and noise.

Leakage Class (per EN 12266-1)

Generally conforms to Class A or B; minimal allowable leakage under test conditions.

Body Material Options

Available in cast iron, ductile iron, carbon steel, or stainless steel constructions.

Design Pressure Class

Commonly rated for PN10, PN16, or ANSI Class 150 pressure classes.

Thermal Expansion Compatibility

Compatible with thermal expansion; requires proper allowances in pipeline design.

Installation Sensitivity

Requires precise alignment; sensitive to torque and pipeline stress during installation.

Control Accuracy

Low control accuracy due to binary open/close operation mode.

Position Repeatability

Moderate repeatability; limited by manual or actuator-driven operation consistency.

Technical Advantages

Gate valves are a solution to flow control problems where minimal resistance and efficient fluid transport are critical. Their wedge-shaped disc design reduces pressure drop, allowing fluids to pass with minimal obstruction, which is essential in large-scale systems like water treatment plants or gas pipelines. This smooth flow characteristic ensures that the valve does not hinder system efficiency, thereby reducing energy costs and preventing wear caused by flow turbulence. In systems where energy efficiency is a priority, gate valves provide a highly effective solution to optimize operational performance.

Gate valves are built to operate under extreme pressure and temperature conditions without compromising performance. They are designed to handle pressures up to several thousand PSI and temperatures reaching over 1000°F, making them ideal for applications in power generation, oil, and gas. The robust construction ensures that the valve can withstand thermal expansion and pressure shocks, offering a reliable solution for systems subject to fluctuating conditions. By selecting gate valves for high-pressure and high-temperature applications, you ensure your system’s longevity and reliability, even under the most demanding circumstances.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure the durability of its gate valves in corrosive environments?

Frigate uses high-quality alloys like stainless steel and Inconel for manufacturing gate valves, ensuring resistance to both corrosion and wear in aggressive environments. The valves are treated with advanced coatings that enhance their resistance to chemicals and extreme conditions. Additionally, precise machining ensures that the seating surfaces are smooth, which reduces the chance of corrosion-related failure. This combination of material selection and surface treatment provides long-lasting performance in corrosive applications.

What testing procedures does Frigate use to guarantee the performance of gate valves under high-pressure conditions?

Frigate conducts extensive hydrostatic and pneumatic testing to verify the gate valves’ ability to withstand high pressures. Each valve undergoes a pressure test at a range of pressures to ensure the integrity of seals and body. The testing process includes verifying the valve’s ability to achieve a complete shutoff under maximum working pressure. These procedures ensure that the valves meet stringent industry standards for safety and performance.

How does Frigate customize gate valves for specific industry requirements?

Frigate works closely with clients to understand the specific pressures, temperatures, and flow rates of their systems. Based on these requirements, the company customizes valve dimensions, materials, and sealing mechanisms for optimal performance. Frigate also offers specialized coatings and modifications for valves used in extreme conditions, such as cryogenic or high-temperature environments. Custom engineering ensures the gate valve operates efficiently and reliably in its intended application.

What materials does Frigate use for gate valves in high-temperature and high-pressure applications?

Frigate employs high-performance materials such as Inconel, Hastelloy, and alloy steel for gate valves in high-pressure and high-temperature applications. These materials offer superior heat resistance, strength, and oxidation resistance, ensuring reliable performance under extreme conditions. The materials are selected based on their ability to retain mechanical properties at elevated temperatures without compromising safety or efficiency. This ensures long-lasting performance, even in the most demanding environments.

How does Frigate handle the issue of thermal expansion in gate valves used in extreme temperatures?

Frigate designs gate valves with materials that have similar coefficients of thermal expansion to prevent stress during temperature fluctuations. The valve components, including the stem and body, are carefully engineered to accommodate thermal expansion without compromising the valve’s function. Specialized materials like carbon steel and stainless steel alloys are often used to maintain the integrity of the valve under extreme temperature variations. This thoughtful design prevents valve failure due to thermal cycling in high-temperature applications.
