V5025A
FLANGED LINEAR VALVE PN25
SPECIFICATION DATA
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
GENERAL
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.
• Easy mounting of direct-coupled electric and
pneumatic actuators
• Approved according to DIN EN 14597 in DN15...80 in
combination with ML6425/ML7425

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.
