Pressure balanced control valve for closed circuit systems. For district heating; hot or cold water (max. 50% glycol), water quality VDI2035; or steam.
These single-seated valves are suitable for use in conjunction with the modulating control of hot / chilled water or steam in closed 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 ML6421/ML7421 or by pneumatic actuators MP953.
FEATURES • Pressure-balanced plug • Nodular iron body with flanged end connections • Low seat leakage rate • Metal-to-metal seating for long life span • Self-adjusting packing • Accurate positioning to ensure state-of-the-art temperature control • Easy mounting of direct-coupled electric and pneumatic actuators • Approved according to DIN EN 14597 in DN15...80 in combination with ML6425/ML7425
