Brilliant chrome pla ting micrometric val ves with thermost a tic option for toweldryers t431c - t432c

Description

The T431C and T432C micrometric valves with thermostatic option are designed with a particular focus on the aesthetics of the product, with rounded forms and brilliant chrome plating on the components. Their principal use is in heating systems for toweldryers and heated towel rails, or wherever a particular look is desired. The T431C and T432C micrometric valves with thermostatic option can be co- ordinated with the T29C and T31C brilliant chrome lockshield valves, which intercept and balance the circuits, leaving the manual valve with the sole task of intercepting the flow when the user does not wish to heat the toweldryer. Versions and product codes Product code Connections Type Corresponding lockshield valve T431CX003 1/2” x 16 angled T29CX003 T432CX003 1/2” x 16 straight T31CX003 Additional accessories T470CX001: brilliant chrome thermostatic head with CLIP CLAP connection For connection to the pipe use adaptors T178C and T179M. 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 . Nut Stem Spring Gasket O-Ring Body In case of malfunction of the valve it is possible to replace the O-ring, by unscrewing the nut using an hexagonal wrench 11 mm R400 If the problem persists is also possible to replace the complete bonnet using the appropriate key R400. Main features Micrometric adjustment The micrometric valves with thermostatic option are characterised by the fact that they allow micrometric adjustment, through which it is possible to partially open a manual function valve. Removing the upper part of the handwheel provides easy access to the graduation scale. Adjustment is carried out by moving the metal pin into the most appropriate position for requirements, in accordance with the dedicated diagrams shown in the section on losses of pressure.
