Optional Accessories for Pneumatic Knife Gate Valve / Pneumatic Slide Gate Valve:
Single or Double Solenoid Valves – Available in 24V, 220V, and other voltages; explosion-proof solenoid valves optional.
Proximity Switches – For position feedback and automation.
Air Preparation Unit (FRL) – Includes pressure regulator, filter, and lubricator.
Electro-Pneumatic Valve Positioner – For precise flow regulation in control applications.
Integrated Design: Streamlined valve body reduces flow resistance and ensures smooth, flexible operation.
Key Feature:
Low-Friction Actuation: Screw drive with dual-plane bearing design greatly reduces transmission friction, allowing easy and smooth valve opening.
Reliable Sealing: Movable sealing seat with preloaded O-ring ensures tight contact with the gate, minimizing leakage. Automatic wear compensation extends seal life in long-term operation.
Guided Gate: Fixed guide pawls with no recess design prevent media accumulation or jamming.
Customizable Sealing Options:
Metal Hard Seal: Gate surface can be chrome-plated or ion-nitrided for enhanced wear resistance.
Soft Seal: Options include PTFE, reinforced PTFE, EPDM, or NBR for corrosion resistance and reliable sealing.
Wide Media Compatibility: Suitable for various fluids. High sealing performance, economic and practical design. Operable via manual, pneumatic, or electric drive, suitable for diverse industrial applications.
