Wellhead equipment spare parts API 6A Gate valves manufacturer API standard

Specifications:

Gate Valves are specifically engineered for the rigorous requirements of oilfield applications. Designed for dependable, heavy duty performance in abrasive service conditions, Demco DM gate valves are commonly selected for a number of oilfield applications, including:

• Pump manifold block valves

• High pressure mud mixing lines

• Standpipe manifolds

• High pressure drilling system

• Block valves

• Wellheads

• Well treating and fracturing service

• Production manifolds

• Production gathering systems

• Production flow lines
  

The ANSI series valves conform to the standard flange dimension and pressure requirements for ANSI classes 400, 600, 900 and 1500. Except for the 4" class 1500, these valves are designed with economical, double acting threaded stem & gate. The 4" 1500 use the same rising stem design used in the 4" 3000 API series valve.

The API series valves conform to the standard flange and pressure requirements for API classes 2000, 3000 and 5000. Except for the 4" and larger API 5000, these valves are designed with heavy duty, double acting rising stems.

Both series are offered with threaded, weld and flanged end connections. End connection availability varies by size and Pressure based on market requirements. Some sizes in the ANSI series are offered with grooved end connections.
