Knife Gate Valve Accessories
Position Sensors
Position sensors utilize proximity probes and a magnetic target to detect the valve position and provide reliable feedback to a control system. Mounting directly to the yoke and detecting the position of the gate provides a more reliable solution than cylinder mounted switches. Hazardous area versions are available.
Solenoid Valve
Solenoid valves are used to control the opening and closing of a pneumatically actuated valve. A NAMUR style valve is typically used for rack pinion style actuators, and an inline valve is used for pneumatic cylinders. They are available with AC or DC coil voltages and with approvals for use in hazardous areas.
Filter/Regulator
A regulator controls the air pressure used to operate a pneumatically actuated valve. Combined with an air filter and auto-drain to remove any condensation in the line, it also provides protection of downstream pneumatic components and improves system reliability.
Positioner
Positioners are used in conjunction with pneumatically actuated valves to allow variable opening and closing for flow control based on process conditions. Different types of positioners are available and including smart positioners with digital programming. Explosion proof versions are also available, as well as stainless steel enclosures for corrosive environments.
Optional Materials
Inconel Gate
Inconel is a nickel-based superalloy known for its exceptional high-temperature strength, oxidation resistance, and superior corrosion resistance.
Hastelloy Gate
Hastelloy C-276 is a nickel-molybdenum-chromium alloy and one of the most trusted materials offering unmatched protection in extreme chemical and offshore services.
