   Gate Valve

Demco Gate valve

 

The premier design in the oil and gas drilling market, Demco Series DM 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 Demco series DM gate valve is offered in two basic pressure classes:

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.

W-K-M Expanding Gate valve

Expanding Gate

The expanding gate valve design uses a two piece wedged shape gate assembly to generate positive sealing. When moved to the opened or closed positions, gate segments expand out to the seats creating a mechanical energized seal for reliable performance. Valves are full bore through-conduit which does not restrict flow. A non-rising stem is used for better control and dependability.

Valves are available in pressure ratings from 2,000 to 5,000psi. Standard bore sizes are from 2 1/16" to 4 1/16". A variety of trim designations and valve styles are described on the next page.

Slab Gate valve

The slab gate valves are available in temperature classes L, P, R, S, T and U specified in API 6A. Gate valves to be used in the 350 ℉ but 650 ℉ higher temperature can be supplied on request. Fire-proof gate valves also can be supplied to API 6A. The pressures grades are from 2000 psi, 3000 psi, 5000 psi, 10000 psi and 15000 psi working pressures, materials classes from AA through FF, products specification levels (PSL) from 1 through 3 and performance requirement (PR) 1.
