Knife Gate Valve WCB Body EPDM Seat 150LB Flanges
The Cematic WCB body EPDM seat knife gate valve is the solution for flow control in lines with solids, slurries, and viscous fluids.
Its A216 WCB carbon steel body provides mechanical robustness. In addition, the EPDM seat ensures reliable sealing and chemical compatibility. Together, they form an ideal combination for demanding industrial processes.
Why choose a WCB body EPDM seat knife gate valve?
The bidirectional knife gate design cleanly cuts through the fluid. For this reason, it is especially effective in fluids with solid particles or high viscosity. Unlike conventional gate valves, it does not retain residue in the internal cavity. Therefore, it reduces cleaning and maintenance times in lines with solids.
Likewise, the EPDM coating protects the metal parts from abrasive wear. Consequently, the valve's lifespan is extended, and corrective maintenance is reduced.
Manual operation with a handwheel allows for simple and direct operation. Furthermore, it is compatible with automation via pneumatic or electric actuator if the process requires it.

Common Applications
The knife gate valve with WCB body is mainly used in systems where a thin but resistant valve is required to control the flow of fluids under demanding conditions. Below are some main applications:
Mining and mineral processing: Designed to handle abrasive slurries, tailings, and pulps in transport, grinding, or separation processes. Ideal for lines with high solids content where erosion resistance and reliable tight shut-off are required.
Power plants and thermal generation: Used in systems for transporting ash, pulverized coal, limestone slurries, and slag suspensions, where conditions are highly abrasive and require a robust valve with an internal rubber lining for greater durability.
Cement and construction materials industry: Suitable for cement mixtures, clinker, slag, and aggregates, providing flow control and effective isolation in dense media or with abrasive particles.
Pulp, paper, and wastewater treatment: Used in handling thick sludges, water with solids, fibers, or sediments, where the knife gate design allows for an unobstructed passage and prevents residue accumulation.
Chemical and petrochemical processes: Recommended for fluids with solid particles, thanks to its internal rubber lining (EPDM) that protects metal parts against wear.
