Description

The R296 mixing valve allows for the interception and mixing of heating fluid in radiant heating and cooling systems and in medium-size radiator heating systems that require precise control of water delivery temperature. The valve is equipped with a handwheel for manual operation, or alternatively, it can be coupled to a K274, K275 or K275-1 actuators for automatic control.

Three-wa y mixing ball val ve r296 Operation R296 + HANDWHEEL FOR MANUAL OPERATION The valve R296 is equipped with a manual handwheel. Due to the graduated scale, the handwheel also functions as a flow indicator. The direction of flow of the heating fluid can be controlled at any time, simply by checking the position of the handwheel:

  • in position 0 the fluid flows entirely through the by-pass.
  • in position 5 the fluid passes through the valve entirely, and is directed towards the system terminals. By-pass Direct way SYSTEM SIDE BOILER ROOM SIDE SYSTEM SIDE BOILER ROOM SIDE SYSTEM SIDE BOILER ROOM SIDE SYSTEM SIDE BOILER ROOM SIDE R296 + ACTUATORS The handwheel can be replaced with the K274Y101, K274Y102, K275Y002, K275Y011 or K275Y013 actuators. In this case the direction of fluid flow can be visually checked both through the actuator, or by removing the actuator and verifying the position of the indicator mark (milling).  Flow direction control through the position of the milling:
  • with milling, in correspondence with the OFF label, the fluid flows entirely through the by-pass.
  • with milling, in correspondence with the ON label, the fluid passes through the valve entirely, and is directed towards the system terminals.

Three-wa y mixing ball val ve r296 Installation

  • The R296 valve must be installed with the command stem in a vertical or horizontal position; installation with the command stem vertical and the actuator positioned beneath the valve is not permitted.
  • The R296 valve must be installed according to the direction of flow as indicated by the arrow present on the valve body.
  • The R296 valve must be installed on the delivery side. The circulator on the secondary circuit must be installed downstream from the mixing valve. System terminals R296 Circulator
  • The mixing valve can be installed with the by-pass to the left or to the right, simply by screwing onto the copper fitting and the return unit on the opposite side of the brass cap. R296 with by-pass to right R296 with by-pass to left Note. For the installation of actuators and their correct setting please refer to the operating instructions of the valves and actuators.
