False 2- way Control Valves type M1F2.3.02- I Cast iron, PN 16, DN 15/ 4 – 50 mmGB- 1 Characteristics • Nominal pressure PN 16 • Regulating capability kvs > 25 kvr • Single- seated, tightly closing • Quadratic characteristic Applications Control valves type M1F are designed for regulating low, medium and high pressure hot water, steam and lubricating oils. The valves are used in conjunction with our temperature or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations. Dimensioning For sizing of control valves and selection of actuators, please see " Quick Choice" leaflet no. 9.0.00. Design The valve components - spindle, seat and cone - are made of stainless steel. The valve body is made of cast iron EN- GJS- 400- 15 with flanges drilled according to EN 1092- 2. The thread for the actuator connection is G1B ISO 228. The valves are single- seated and designed for tight closure. The leakage rate is less than 0.05% of the full flow ( according to VDI/ VDE 2174). Quality assurance All valves are manufactured under an ISO 9001 certification and are pressure and leakage tested before shipment. For marine applications the valves can be supplied with relevant test certificates from recognized classification societies. Function Without the actuator being connected, the valve is held in open position by means of a spring. With pressure on the spindle the valve will close. In connection with our thermostats or electronic actuators, the valves will close at rising temperatures. For cooling circuits a reverse acting valve can be used. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.

False 2- way Control Valves type M1F Cast iron, PN 16, DN 15/ 4 – 50 mmGB- 2 2.3.02- I Definition of kvs- value The kvs- value is identical to the IEC flow coefficient kv and defined as the water flow rate in m3/ h through the fully open valve by a constant differential pressure, ?pv, of 1 bar. Mounting The valves can be installed with verti-cal as well as horizontal spindles. For valve temperatures of max. 170 º C, the thermostat/ actuator can be fitted below or above the valve. For valve tempera-tures above 170 º C, a cooling unit of type KS has to be applied with connection downwards - according to the following instructions: Valve Cooling Suitable Temperature Unit for 170 º C - 250 º C KS- 4 All actuators 250 º C - 300 º C KS- 5 Thermostats 250 º C - 300 º C KS- 6 Valve Motors KS- 5 or KS- 6 must be applied to hot oil systems. Strainer It is recommended to use a strainer in front of the control valve if the liquid contains suspended particles. Accessories Manual Adjusting Device The device has a built- in stuffing box. For sealing and manual operation of valves when an actuator has not been fitted, e. g. during periods of construction. Cooling Unit KS- 4 Cooling unit protecting the stuffing box of the motor/ thermostat. To be applied at valve temperatures between 170 º C and 250 º C. Cooling Unit KS- 5 Cooling Unit KS- 6 Cooling units with built- in bellow glands, replacing stuffing box of thermostat ( KS- 5) or valve motor ( KS- 6). Must be applied at valve temperatures above 250 º C and in hot oil systems.
