Wedge gate valve

Solid wedge gate valve / flexible wedge gate valve​

Wedge gate valves are mostly metal to metal sealing valves where the wedge is screwed down until it is stopped by the seats which are placed under a slight angle. ​

Smaller valves typically have a solid wedge, where bigger ones have a “flexible” wedge. The wedge is flexible so it can it can adapt to the seats without requiring to much force or to have a (quicker) sealing between gate and seat.​

Various design variations are possible: bolted bonnet (the most common), welded bonnet for high pressure forged gate valves, the cast equivalent is a pressure sealed bonnet. ​

Standards typically used with gate valves:​
API 600 the standard for cast gate valves 1”-24”​
API 602 the standard for forged gate valves ¼”-4”​
API 603 the standard for corrosion resistant light wall gate valves ½”-24”​
BS 1414 the Britsh Standard for gate valve (replaced by EN ISO 10434) ¼”-24”​
EN ISO 15761 the European standard for forged gate valves ¼”-4”


Demco, part of the Cameron valve division was established in 1947.

Standard features

As one of the most durable resilient-seated butterfly valves in the industry, the Cameron butterfly-style DEMCO valve excels in a variety of applications.
Cast in both wafer and tapped lug patterns in a variety of material choices, butterfly-style DEMCO valves feature a one-piece body for reduced weight and increased strength.
The unique stem hole design in the disc ensures a dry stem journal. The hard-backed seat enables ease of installation, reliable operation, and infield repairability without special tools. Butterfly-style DEMCO valves are available in sizes 2 to 36 in [50 to 900 mm].
Engineered for long-term, reduced-maintenance performance, butterflystyle DEMCO valves are commonly selected for a variety of applications in the following industries:

  • chemical and petrochemical
  • agriculture
  • oil and gas drilling and production
  • food and beverage
  • water and wastewater
  • cooling towers (HVAC)
  • power
  • mining and materials
  • dry bulk handling
  • marine and government.

Bidirectional sealing

The butterfly-style DEMCO valve provides bidirectional sealing at full-rated pressure with identical flow from either direction.

Integral flange seal

An integral flange seal molded into the edge of the seat accommodates ASME weld neck, slip-on, threaded, socket, and stub-end type C flanges.

ASME Class 150 rating

With a body rating of American Society of Mechanical Engineers (ASME) Class 150 (285-psi nonshock), the wafer body diameters are designed to self-center in the ASME Class 150 flange pattern.

WKM has been one of Cameron’s strongest brands since its Flow Control Division acquired it in 1987. The name is trusted among engineers in the industry field because of its stellar track record that has remained constant for more than a century. Their line of ball, butterfly and gate valves have repeatedly delivered positive results in many oil and gas and process controls applications, no matter where they are installed. One of the things that make WKM great is that even though their line is in no ways the cheapest, over the course of time their easy to repair design and replaceable parts make their operating costs lower than many other traditional valves that are less expensive at the initial time of purchase.
