Specs of API 602 Gate Valve

Wall Thickness

The wall thickness of the API 602 Gate Valve is built to meet the specific requirements of the API 602 standard. This standard allows the valve to withstand high-pressure environments. For example, thicker walls are essential in applications where the valve must endure harsh conditions. NTVAL adheres to these specifications to provide a product that performs reliably in demanding situations.

Pressure-Temperature Ratings

The API 602 Gate Valve is designed according to ASME B16.34 standards for pressure and temperature ratings. This means the valve can operate efficiently under various pressures and temperatures. The ratings allow the valve to perform well without leaking or failing, even in challenging conditions. These ratings are critical in selecting the right valve for specific needs.

General Valve Design

The general design of the API 602 Gate Valve follows API 602 and ASME B16.34 guidelines. This design includes features that make the valve dependable, such as tight sealing and easy operation. The valve’s design allows it to handle oil, gas, and chemicals. But wait, there’s more! This versatility makes it a go-to choice for industries requiring a reliable valve solution.

End-to-End Dimensions

The API 602 Gate Valve’s end-to-end dimensions are in line with ASME B16.10 standards. This specification certifies that the valve fits seamlessly into existing piping systems without requiring significant modifications. Accurate end-to-end dimensions are crucial for maintaining the flow and pressure of the system.

Features of API 602 Gate Valve

Wedge Guides

Special Material Valves are built from materials like titanium and monel, which offer excellent resistance to corrosion. This makes them ideal for use in harsh environments where exposure to chemicals, saltwater, or other corrosive substances is common. The ability to withstand such conditions helps in extending the valve's lifespan.

Seats and Seals

The seats and seals of the API 602 Gate Valve are designed to provide a tight, leak-free closure. These components are made from durable materials that can withstand harsh conditions. The quality of the seats and seals is crucial for maintaining the valve’s performance, making sure that it effectively controls the flow of fluids without leakage.
