Description

Radiator lockshield valve type 456 with drain, shut-off and adjustment function. With cap (version M) to protect against incorrect operation. Adjustable according to flow diagram (see operating instructions). The selected setting is reproducible due to the integrated stroke limiter/stop (not version M Eco) and thus independent of draining. The optional filling and draining unit FEV with hose connection G½ can be used for easy and fast draining. Draining capacity equal to flow coefficient 1.1. Versions M Eco without stroke limiter.
