The Johnson Controls VG7243ET+3008BP is engineered as a control valve featuring a pneumatic actuator. This device is made from cast bronze and weighs 5.7 lbs, making it a lightweight yet robust choice for various fluid regulation applications. The valve adopts a two-way design that functions in a normally open setting, with a push-down-to-close operation, allowing for straightforward manipulation of fluid flow in the system.
Designed with a size of 1/2 inch, the VG7243ET+3008BP uses NPT threaded end connections for compatibility with standard pipe fittings. The valve’s trim is crafted from stainless steel, ensuring a reliable and efficient flow characteristic rated as equal percentage. The control port has a Cv rating of 1.8, positioning the valve well for moderate control needs.
At the heart of this control valve is a V-3000-8012 pneumatic actuator, which is exposed for easy accessibility. Accompanying this actuator is a V-9502 positioner that optimizes the valve's performance. The actuator operates within a spring range of 3 to 6 psig, providing flexibility in various operational contexts. The maximum closeoff pressure for the VG7243ET+3008BP is rated at 299 psig (2,060 kPa), indicating its capability to handle significant pressure conditions.
The operational fluid temperature for this valve spans from 2 to 170 °C, accommodating both water and saturated steam applications at pressures up to 100 psig. The valve is designed to operate effectively between a minimum operating temperature of 2 °C and a maximum of 65 °C. In addition, the valve features impressive rangeability of over 100:1, enhancing its adaptability for numerous applications, making it a versatile choice for control needs.
