Common questions on this part
The standard 4M-NGM is a uni-directional valve engineered to seal tightly with line pressure pushing the blade against the seat. For applications with potential backpressure or reversing flow, a bi-directional sealing version with dual elastomer seats is available on order.
Yes. 4MATIC knife gate valves feature a standardized superstructure bracket that allows easy retrofitting with double-acting pneumatic cylinders, NAMUR solenoid valves, and magnetic proximity limit switches.
