Automation Accessories

A valve becomes an automated valve only when the right accessories are fitted around it. 4ma Valves Automation offers pneumatic actuators, limit switch boxes, solenoid valves, filter regulator units, electro pneumatic positioners and air volume boosters, so you can build a complete valve automation package from one supplier.

Our accessories are used in pharmaceutical, food, dairy, beverage and chemical plants, where valves must open, close and report their position reliably, cycle after cycle.

Types of Automation Accessories by 4ma

• Pneumatic Actuator: Single acting, double acting and scotch yoke actuators that open, close or modulate ball and butterfly valves using compressed air.
• Limit Switch Box: Micro, standard and stainless steel boxes that confirm whether a valve is open or closed, both visually and electrically.
• Solenoid Valve: NAMUR solenoid valves in spool, poppet and direct acting types that direct compressed air to the actuator on an electrical signal.
• Filter + Regulator Air Combination: Filter regulators, air F+R combinations and air lock valves that clean and regulate the air supply.
• Electro Pneumatic Positioner: Linear and rotary feedback positioners that convert a control signal into precise valve positioning.
• Air Volume Booster: A booster that increases air flow to speed up the response of larger actuators.

How Automation Accessories Work Together

In a typical automated valve, compressed air first passes through a filter regulator to remove moisture and dirt and hold a steady pressure. A solenoid valve then directs that air to the pneumatic actuator, which turns the valve. A limit switch box sends the valve’s open or closed position back to the control system. Where the process needs throttling instead of simple on-off action, a positioner and, for large actuators, an air volume booster give faster and more precise control.

Applications of Automation Accessories

These accessories are used wherever valves need to work without an operator at the valve: CIP/SIP systems, filling lines, dosing systems and general hygienic process automation. Fail-safe actuator options let a valve return to a safe position if the air supply is lost.
