The CTV valve range is intended to be used in conjunction with the RTA thermal actuators for temperature control in heating and cooling systems, such as radiators, convectors, chilled ceilings etc. The valves are supplied with a grey plastic cap which can be used to open/close the valve manually during system installation. Turning the plastic cap clockwise to its end position closes the valve. Adjustable kvs-value.
