The lockshield valve is used as a shut off valve or pre-setting valve on radiators. The lockshield valve RRVR and RRVV is equipped with two cones, one for shut off and one for pre-setting. Pre-seeting is carried out without draining the system. The lockshield valve is restricted so that the cone cannot be unscrewed unintentionally. RVR and RVV is equipped with one cone for closing and has an o-ring of EPDM rubber.
