Product Description
These single-seated valves are suitable for use in conjunction with the modulating control of hot / chilled water or steam in heating, ventilating, and air conditioning systems. They are designed especially for use in high differential pressure applications (e.g. district heating) and can be operated by linear actuators ML6420/ML6425, ML7420/ML7425, or M6421/M7421 or by pneumatic actuators MP953.
