283-06050

The Siemens part number 283-06050 is an assembly combining a control valve with a pneumatic actuator. Rated with a flow coefficient of 63 Cv, this assembly effectively controls fluid movement in various applications. It incorporates an 8-inch pneumatic actuator featuring a spring-return mechanism, which ensures reliable operation. This actuator comes with a factory-mounted positioner for optimal performance in flow regulation.

The actuator’s spring range offers a fixed span of 5 psi, with an adjustable starting point between 3 and 10 psi, accommodating a variety of system requirements. The valve, designed as a normally closed unit, contributes to efficient flow control with a linear action pattern. Its nominal size measures 2-1/2 inches (65 mm).

The construction of the valve body utilizes cast iron, while the trim is made of stainless steel, providing durability and corrosion resistance. Rated at ANSI Class 125, the valve is built to withstand substantial pressure levels. It can perform well in media temperatures ranging from -7°C to 120°C.

The assembly's enclosure rating is NEMA 1, indicating it is suitable for indoor applications without exposure to weather elements. It is operational and can be stored in ambient temperatures spanning from 2°C to 85°C. The leakage class is rated at ANSI Class IV, allowing minimal leakage of only 0.01% of the Cv, and it features a 1/8-inch NPT connection for actuator air supply.
