1 PT series valves 090E une 08 R0PT R0PT RPT RPT R0PT RPT escription The PT valves with thermostatic option and presetting are used to slice the delivery water flow rate in a radiator. hen the special worksite protection handwheel is fully closed, it is possible to exceed static pressure values of 0 bar with the system disabled. n any case, it is advised to connect the heating elements before carrying out the pressurised seal tests on the system.

These valves can be pre-set to efficiently balance the circuit. y combining them with radiator thermostatic heads and chronothermostats they offer great energy saving. The bonnet has a numbered bush: position 0, (single notch) (fully open). To make the presetting, proceed as follows: ote. To adjust the flow rate of the valve, use the RPY00 key. Remove the red worksite protection using a screwdriver.

3 PT series valves 090E une 08 Replacement of PX00 bonnet arning. ith 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. Unscrew the valve bonnet by turning the R00 llen key with a mm llen spanner. Push the stem slightly while performing this step to prevent the bonnet from detaching. Refer to the R00 llen key instructions. R00 n case of malfunction of the bonnet (PX00) is possible to replace it, using the appropriate key R00. R00 mm To replace the bonnet, proceed as follows: Remove the ** numbered ring using pliers for elastic rings (seeger). R00 mm mm mm Tighten the ball valve using a mm llen spanner, purge the water from the E drain and remove the R00 llen key stem together with the bonnet to be replaced. Refer to the R00 llen key instructions. E ove the stem of the R00 llen key about half the way back. Fit the plastic threaded ring connecting it to the valve body pins. Screw the R00 llen key on the ring nut and install the valve bonnet with the R00 stem, fitting it in correct position. Refer to the R00 llen key instructions. R00 mm mm E R00 mm R00 mm Remove the mm PX00 bonnet and E 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 must face the radiator. ow is possible to make the new presetting as described in the paragraph Valve presetting. mm E
