267-05981

The Siemens 267-05981 control valve assembly is designed for reliable performance in various system applications. It integrates the SKD60U actuator and operates effectively with a voltage rating of 24 Vac, while accommodating frequencies of 50 and 60 Hz. The ambient temperature range for this model is -15°C to 55°C, making it suitable for diverse installation environments. The valve also handles medium temperatures ranging from -7°C to 120°C, enabling versatility in fluid management.

This assembly is sized at 3 inches, with an impressive flow coefficient of 100/86 Cv, indicating its capability for significant flow regulation. For control, it operates on a proportional signal, accommodating input ranges of 0 to 10 Volts DC or 4 to 20 mA. The unit is designed as a non-spring return valve, which aids in consistent operation.

In terms of construction, the valve body adheres to ANSI Class 125 standards, contributing to its robust build quality. The assembly boasts a leakage rating of ANSI Class IV, which signifies minimal leakage at 0.01% of the Cv rating, ensuring efficiency in operation. The housing features a die-cast aluminum actuator, while the valve body is composed of cast iron, complemented by bronze trim materials. Its nominal force specifications include 225 lbf at 0% opening and 258 lbf at full opening (100%), translating to approximately 1000N and 1150N respectively. This control valve assembly is built for reliability and precision, suitable for various industrial applications.
