Combination valve for water heating.
Design
Valve body made from DZR-brass, EN 12165 CW602N, with combined shut-off and check valve.
- Max pressure: 1.0 MPa
- Max working temp: 90°C
Fitting / Installation
The arrow on the valve housing indicates the direction of the flow. The connection with female thread G½ is designed for LK Armatur’s system with o-ring seals. Other articles are fitted in the usual manner.
Compression fittings for fitting to copper or steel pipes. For fitting to a male thread connection, adapter LK 373 15 x G½, art.no 189 8022 or LK 373 22 x G¾, art.no 189 8055 is used.
It is easier to fit the compression fitting if a lubricant is applied to the thread and bevel. Tighten first by hand and then with a box spanner. Soft pipes are to be fitted with a support sleeve.
Operation and maintenance
The shut-off/check valve requires no maintenance.
The installation should be checked regularly.
