KFD - Series D Flexgate Actuated Knife Gate Valve

Brand: Red Valve Company, Inc

Red Valve's Series D Pneumatic Actuated Flexgate Valves are available with pneumatic, electric or hydraulic actuators. Other options include limit switches, solenoids and air regulators.

The actuated Flexgate Valve provides long-term abrasion resistance under high-cycle conditions. The valve self-cleans each time it is cycled and is ideal for automated operations.

Red Valve manufactures its pneumatic actuators using black Amalgon, a fiberglass-reinforced epoxy resin.

The actuator material is inert to most corrosive chemicals, hydraulic fluids, water and oil. It has an operating temperature range from -90° to 225° F and can withstand maximum working pressures of 250 psi.

Inside the actuator walls are polished and impregnated with molydisulfide for reduced friction and wear.

The piston seal is a long-lasting O-ring. The piston rod is sealed with a lip seal, which is protected by a rod wiper ring. This wiper ring prevents dirt from being dragged through the seal.
