Expansion Gate Valve

Product Overview: The Expanding Flat Gate Valve features a specialized expanding gate mechanism engineered to deliver a tight, forced mechanical seal in demanding high-pressure environments. Rated for operating pressures from 2,000 PSI up to 10,000 PSI, this heavy-duty valve provides high-integrity isolation for oilfield wellheads, Christmas trees, gas production trees, and manifold systems.

Key Features & Advantages:

• Expanding Gate Technology: Mechanical expansion design ensures a positive, zero-leakage seal against both seats regardless of differential pressure.

• Severe High-Pressure Performance: Optimized for critical gas and oil production environments up to 10,000 PSI.

• Extreme Temperature Tolerance: Operates reliably in harsh thermal conditions ranging from -60°C to +345°C (Temperature Class K to Y).

• Versatile End Connections: Available with Ring Type Joint (RTJ) flanged, threaded, or clamped end connections to suit specific piping configurations.

• API 6A Certified Quality: Manufactured to strict specification levels (PSL1–PSL3) and material grades to resist corrosion and wear.
