Description

The PTG valves with thermostatic option and presetting are used to slice the delivery water flow rate in a radiator. When the special worksite protection handwheel is fully closed, it is possible to exceed static pressure values of 10 bar with the system disabled. In any case, it is advised to connect the heating elements before carrying out the pressurised seal tests on the system. LEFT version: frontal thermostatic head connection and supply from below; valve to the left of the radiator. RIGHT version: frontal thermostatic head connection and supply from below; valve to the right of the radiator. Spare parts

• P12AX006: spare parts kit (bonnet, numbered ring, regulation key, instrucion) for PTG series valves.

ValVes with thermost a tic option for radia tors, with presetting Valve presetting PTG valves are equipped with a special bonnet (P12AX006) which determines a specific flow section based on the position set, thus generating the desired pressure losses within the hydraulic circuit. These valves can be pre-set to efficiently balance the circuit. By combining them with radiator thermostatic heads and chronothermostats they offer great energy saving. The bonnet has a numbered bush: position 0,5 (single notch) - 1 - 2 - 3 - 4 - 5 - 6 - 7 - N (fully open). To make the presetting, proceed as follows: Note. To adjust the flow rate of the valve, use the R73PY010 key. 1 Remove the red worksite protection using a screwdriver. The stem “B” is positioned on N (fully open). A BB N 654 3 3 N 654 N

2 Set the R73PY010 key on the bonnet stem, fitting it in the only position

allowed (letter “N” visible from the slot of R73PY010 key and facing the reference “A” on the valve body). A BB N 654 3 3 N 654 N

3 Turn the bonnet stem using the key R73PY010 until the desired presetting

number number appears from the slot of the key. A BB N 654 3 3 N 654 N

4 Remove the key R73PY010, the stem “B” will be on the desired presetting

position, marked by the number on the valve ring. Adjustment positions 0,5 (single notch) - 1 - 2 - 3 - 4 - 5 - 6 - 7 - N (fully open). A BB N 654 3 3 N 654 N Technical data

3 Unscrew the valve bonnet by turning the R400 Allen key with a 6 mm

Allen spanner. Push the stem slightly while performing this step to prevent the bonnet from detaching. Refer to the R400 Allen key instructions. 6 mm A R400 D EA C B 5 mm

4 Tighten the “D” ball valve using a 5 mm Allen spanner, purge the water

from the “E” drain and remove the R400 Allen key stem together with the bonnet to be replaced. Refer to the R400 Allen key instructions. 6 mm A R400 D EA C B 5 mm

5 Remove the P12AX006 bonnet and reassemble it inside the valve in

reverse order. Once completed this step, reassemble the numbered ring on the valve paying attention to the position of the numbers: the letter “N” must face the radiator. Now is possible to make the new presetting as described in the paragraph “Valve presetting” . 6 mm A R400 D EA C B 5 mm Replacement of P12AX006 bonnet Warning. With thermostatic head installed on the valve body, to avoid excessive loads on the seal gasket of the thermostatic bonnet (with the resulting risk of jamming and locking) during the summer, it is recommended to place the handwheel of the thermostatic head in the fully open position, marked by the symbol . R400 In case of malfunction of the bonnet (P12AX006) is possible to replace it, using the appropriate key R400. To replace the bonnet, proceed as follows: 1 Remove the *A* numbered ring using pliers for elastic rings (seeger). 6 mm A R400 D EA C B 5 mm 2 Move the “B” stem of the R400 Allen key about half the way back. Fit the “C” plastic threaded ring connecting it to the valve body pins. Screw the R400 Allen key on the ring nut and install the valve bonnet with the R400 stem, fitting it in correct position. Refer to the R400 Allen key instructions. 6 mm A R400 D EA C B 5 mm
