FLANGED LINEAR VALVE PN25/40

SPECIFICATION DATA

GENERAL

These single seated valves are used for modulating control of
hot or chilled water or steam in heating, ventilating, and air
conditioning systems and can be operated by electric linear
actuators as ML6420/25 or ML7420/25 and ML6421/ML7421,
or by pneumatic actuators MP953.

FEATURES

• Cast iron or cast steel 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

• Direct-coupled electric and pneumatic actuators for

easy mounting

• Approved according to DIN EN 14597

INSTALLATION

• Water should meet VDI 2035 requirements.

• Do not install valve with stem below the horizontal.

• Fluid flow must correspond with the arrow direction on the

valve body.

• The installation of a strainer is strongly recommended.
