Overview
RF15 is a three-way control valve with a grey cast iron body, EN 1092-2 flanges, a brass cone and a CrMo steel spindle. It mixes or diverts water and water-glycol mixes in heating, cooling and ventilation circuits. It is offered in Kvs 0.63, 1.0, 1.6, 2.5 and 4.0. Port A to AB has an equal percentage characteristic and port B to AB is linear. A blank flange (BF) on port B turns it into a two-way valve. The stem seal is a maintenance-free EPDM O-ring pack and seat leakage is class VI to EN 1349. It is operated by the Kieback&Peter MD100-RE or MF100-SR family of actuators. With the spring-return MF100-SR, port A stays open if the power fails.
