Can this valve be used in systems with high-pressure refrigerants

it is typically rated for up to 15 HP at 230V and 25 HP at 460V/575V for three-phase applications

Reduced Standby Loss: Closes the vent when the system is idle

ensuring the actuator overcomes friction and fluid pressure to reach the exact position requested by the pneumatic controller

and fluids up to 300 SSU viscosity

Siemens Building Technology 331-4810 Actuator 320735-701 Can this valve be usedThe Siemens 331 4810 is a rugged, metal fabricated No. 3 Pneumatic Actuator engineered for reliable modulating or two position control of HVAC dampers and terminal units. Built with all metal construction and a totally enclosed housing, this 331 Series actuator is a staple for contractors maintaining mixing box dampers, unit ventilators, and air valves. It features a 2 3 8 inch stroke and a nominal 8 13 psi spring range, allowing for precise
