Knife Gate Valves
Series DX Slurry Knife Gate Valve
Series DX slurry knife gate valve features replaceable valve sleeves that are abrasion resistant and a design that allows for slurry discharge, resulting in a clear seat area and gate path. This unique knife gate valve design makes the Series DX perfect for your toughest slurry applications.
When the valve opens, the Series DX reinforced elastomer sleeves seal against each other and provide a 100% full port opening, which minimizes turbulence, which in turn eliminates wear. The seats isolate and protect all metal parts of the valve from coming in contact with the process. When the valve is closed, the sleeves provide a drop tight seal.
Each time the valve strokes, the Series DX Valve is designed to discharge a small amount of slurry out of the valve, which keeps the gate path and seat area clear of entrapped particulates, which might otherwise prohibit the valves ability to close.

Series G Knife Gate Valve
Series G knife gate valve can be fitted with a variety of actuators, including standard handwheel, bevel gear, pneumatic actuators, hydraulic actuators, electric actuators and chainwheel actuators. The Series G has a double-lead ACME thread that reduces operating torque. Limit switch, solenoid valve and bonnet options are also available.
This compact valve is highly resistant to chemical and corrosive flow. Its design affords the user a high-quality valve in which all the wetted parts, including the gate, seat, packing gland and flange face are stainless steel while providing cost savings with cast iron flanges.
Large diameter Series G knife gate valve is a good choice for mining and power generation – it also makes an excellent valve for flood control and pumping stations.

Flexgate
Flexgate slurry knife gate valve is strongly suited for difficult abrasive slurry services in the chemical and power industries.
Flexgate valve is designed with a cast iron body or fabricated steel body, stainless steel gate, and two heavy-duty elastomer cartridge slurry seats. The port is formed by two heavy duty cartridge elastomer slurry seat halves. The cartridge slurry seats are available in various elastomers for chemical compatibility and abrasion resistance. A flush area at the valve's base provides a clean-out port. The Flexgate valve provides bi-directional shutoff. A heavy-duty topworks is standard.
Add-ons to the valve package include electric and hydraulic actuators, limit switches, solenoids, air regulators and chainwheels.
