Functional principle The medium entering the valve (inlet port A) passes through the variable presetting opening (5) which is connected to the ring with the dial (2) for presetting the desired maximum volumetric flow. Then, the medium flows through the flow control valve (6) with a linear characteristic and a stroke of 2.5 mm (DN 10…15) respectively 5 mm (DN 20). Ring with dial for presetting (2) The actuator (not shown here) opens and accurately positions the control valve (6).

Accessories Product no. Stock no. Description Electronic manometer excluding measuring lines and measuring tips. Measuring range 0-700 kPa. A differential pressure of more than 1000 kPa will destroy the pressure sensor. For measuring the differential pressure between P+ and P- of the Combi valves (refer to diagram under "Functional principle" on page 3).

Sizing Engineering example Basis of calculation 1. Determine energy demand Q [kW] 2. Determine temperature differential ΔT [K] 3. Calculate volumetric flow v̇= Q[kW] ∙ 1000 l 1,163 ∙ ∆T[K] h 4. Select suitable Combi valve - pipe connections (internally or externally threaded) - with or without P/T ports 5. Determine dial setting using volumetric flow/dial presetting table, see the following page Example 1. Given is a heat exchanger with 2. Temperature differential (supply - return) 3.
PAGE 8
Volumetric flow/dial presetting Tables to determine the dial setting for a desired volumetric flow. Dp min [kPa] based on volumetric flow; interpolate missing values. The presetting tables indicate the expected nominal volumetric flow. During commissioning, check whether current pre-settings correspond to the planned design. Further adjustment of the pre-settings may be required to achieve the needed volumetric flow.

Installation notes Prior to mounting the actuator, the presetting is to be made as follows: Presetting DN 10…32: 1. Remove control knob from Combi valve. 2. Loosen knurled nut. 3. Adjust the desired dial setting with the white knob. 2. Adjust the desired dial set- 3. Retighten spindle head - ting with the white knob. by hand only 4. Retighten knurled nut by hand. 1.

Manual control When turning the manual control knob in counter-clockwise direction or manually operating the actuator, the valve opens. The actuator closes the valve. The valves are supplied fully open. The manual knob is not designed for permanent manual operation. Maintenance notes The V..P46.. PICV valves are maintenance-free without cartridge. Valve plug, stem, presetting, diaphragm etc.

Application examples Combi valves in HVAC systems combined with variable speed pumps provide even higher energy efficiency. When sizing the pump, it must be made certain that the most critical branch or consumer in the system – usually the remotest from the pump – gets enough pressure (pump head). Thus, it is recommended to use a variable speed pump in constant-pressure mode with end-point feedback, to maintain a minimum differential pressure across the critical valve.
