The MIL Controls 7400 Pneumatic Positioner is a precision device designed to ensure that a control valve's plug position is directly proportional to the controller output pressure, regardless of packing box friction, diaphragm actuator hysteresis, or off-balance forces on the valve plug. This force-balanced system provides a linear relationship between valve position and controller output signal, converting stroke (a length) and force (pressure on a given area) to a common proportionality. The positioner is equipped with a bypass valve that allows for direct application of the controller signal pressure to the bellows, facilitating normal operation.

The MIL Electro Pneumatic Valve Positioner is a precision device used to control the position of a valve in response to an electrical signal. It converts an electrical input signal (typically 4-20 mA) into a pneumatic output signal, adjusting the valve’s position accordingly. This positioner ensures accurate valve operation by compensating for factors like friction, actuator backlash, and changes in system pressure. It provides precise control in applications like oil & gas, water treatment, and chemical processing. The MIL Electro Pneumatic Valve Positioner is known for its reliability, robustness, and ability to work with a wide range of valve types.

A Single Plate Check Valve is a type of valve designed to allow fluid to flow in one direction only, preventing backflow in pipelines. It features a single disc or plate that moves within the valve body to block the reverse flow when pressure drops. The valve opens automatically when the fluid flows in the correct direction and closes to prevent backflow when the flow direction reverses. Single plate check valves are typically used in applications where space is limited, offering compact design and reliable operation, making them ideal for systems like water treatment, HVAC, and oil & gas pipelines.

An Automatic Recirculation Valve (ARV) is a specialized valve designed to protect pumps from damage caused by low flow or dry running conditions. It automatically diverts a portion of the fluid from the pump's discharge line back to the suction side when the flow rate drops below a preset level, ensuring the pump operates within its safe range. ARVs are commonly used in pumping systems, such as in water treatment, HVAC, chemical processing, and oil & gas industries, where they help to prevent pump cavitation, overheating, and subsequent damage. The valve automatically adjusts based on the system's flow conditions.

The MIL 21000 Series is a range of heavy top-guided, single-seated control valves designed for precise regulation of fluid flow in various industrial applications. These valves are particularly well-suited for handling a wide variety of process fluids, including steam, water, gas, and oil, across different industries such as power generation, chemical processing, and petrochemicals.

The MIL 4100 Series Heavy Duty Cage Guided Control Valves are engineered for high-performance fluid regulation in demanding industrial applications. These valves are particularly effective in handling severe service conditions, including high-pressure drops and challenging flow media.

A Recirculation Valve is a type of valve used to redirect a portion of the flow from a system back into the process or storage tank to maintain optimal pressure and flow conditions. It is commonly used in systems where excess flow needs to be returned, such as in cooling, pumping, or filtration systems. The valve helps maintain system stability by controlling the recirculation rate, preventing overpressure and ensuring efficient operation. Recirculation valves are used in various industries, including water treatment, HVAC, chemical processing, and power generation, where controlling the flow and pressure is crucial for performance.

A Double Acting Pneumatic Actuator is a type of actuator that uses compressed air to provide linear or rotary motion. It operates with two air ports—one for extending the actuator (opening) and the other for retracting it (closing). This design provides higher force output and precise control over the movement of valves or dampers in various industrial applications. Double acting actuators are widely used in systems requiring quick, reliable, and controlled operations, such as in the oil and gas, power generation, and water treatment industries. They offer better performance compared to spring-return actuators, especially in high-demand environments.
