False Balanced 2- way Control Valves type H1FB Cast steel, PN 40, DN 25 – 80 mmGB- 2 2.4.03- G Definition of kvs- value The kvs- value is identical to the IEC flow coefficient kv and defined as the water flow rate in m 3 / h through the fully open valve by a constant differential pressure, ?p V of 1 bar. Mounting The valves can be installed with vertical spindles as well as horizontal spindles. For valve temperatures above 170 º C, a cooling unit of type KS has to be applied with connection downwards according to the following instructions: Valve Temperature Cooling Unit Suitable for 170 º C - 250 º CKS- 4All actuators 250 º C - 350 º CKS- 5Thermostats 250 º C - 350 º CKS- 6Valve 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 tightening 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. Subject to changes without notice.

False V2, V4 and V8 Thermostats3.4.01- I Self- acting Temperature ControlsGB- 1 Characteristics • Closing force 200 N, 400 N and 800 N • For heating or cooling valves • Sturdy and reliable • Temperature range 0 to 160 º C (- 30 to 280 º C on request) Applications The temperature controller, which con-sists of a thermostat and a valve, is used for controlling the temperature in central heating systems, district heating systems, industrial plants or industrial processes and in marine systems. It can be used for the control of cold or hot water, steam or oil in heating as well as cooling systems. Function The adjusting cylinder of the thermostat is set at the required temperature for the heating medium in º C. This setting can be fixed, if required. The temperature control is carried out by the thermostatically con-trolled valve reducing or increasing the flow of the heating ( or cooling) medium. The sensor and the capillary tube, which are filled with a liquid, constitute - together with the adjusting cylinder - a closed system. If the temperature of a medium to be heated is above the required level, the temperature of the sensor liquid rises and expands, causing the piston of the thermostat to act upon the valve, reducing the flow of the heating medium. If the temperature of the medium to be heated is below the required level, the temperature of the sensor liquid falls, reducing the volume of the liquid, so that the piston allows the valve to open under its internal spring, thus increasing the flow of the heating medium. The neutral zone of a thermostat is the temperature difference which can occur at the sensor without any movement of the valve spindle. This represents the sensitivity of the control system to tem-perature changes: V2 = 2.5 º C, V4 = 2 º C and V8 = 1.5 º C. Design Thermostat A thermostat consists of a sensor and a capillary tube, filled with liquid, and an adjusting cylinder. The thermostat type designations and technical data are specified in fig. 2. With temperatures above 170 º C, a cooling unit must be fitted between the valve and the thermostat - see fig. 1. The thermostat is self- acting and works on the principle of liquid expansion, it is sturdy in its design, and works with a large closing force. Sensor The following sensor types are available - see fig. 4: 4.1. Rod/ spiral sensor in copper or stainless steel with threaded con-nection according to ISO R7/ 1. 4.2. Spiral sensor ( copper only) with air duct flange. 4.3. Rod/ spiral sensor with steel flange DN 50, PN 40 and DN 50, PN 160. 4.4. Sensor without connection. Usually used with capillary pack box for temperature control in tanks. Capillary Tube The capillary tube is made of copper, stainless steel, or of PVC- coated copper - see fig. 3, but can also be delivered with a flexible iron tube protection. Valve A wide range of valve types for heating as well as cooling systems can be delivered. See the “ Quick Choice” leaflet no. 9.0.00 and datasheets for the valves in question.
