IMI Calypso 15mm Straight TRV & Lockshield Pack (9690-62.800)

The IMI Calypso Straight TRV & Lockshield Pack, consists of a Calypso TRV body, DU head and lockshield valve. Designed for application in a two-pipe pumped heating system. The Bi-directional thermostatic radiator valve can be fitted either vertically or horizontally in the flow or return and either end of a radiator giving the installer total flexibility.

The TRV pack Calypso exact is applied in two-pipe pumped hot-water heating system with normal to high temperature spread, as well as in cooling systems. The valve has a wide flow range as well as optimised noise behaviour and very tight flow tolerances. In extensive systems, even water distribution should be maintained not only during specified normal operation, but also after a drop in room temperature or a break in operations, in order to avoid under or over-supply to parts of the system. To achieve this, the valve characteristic is designed so that the radiator mass-flow does not exceed about 1.3 times the nominal flow even at Preset 8 and with a fully-open valve.

• Corresponding to the standards EnEV and DIN V 4701-10, the thermostatic valve bodies can be designed with a p-band of up to max. 1 K or max. 2 K.
• The Bi-directional thermostatic radiator valve can be fitted either vertically or horizontally in the flow or return and either end of a radiator giving the installer total flexibility.
• The angle kit can be installed as angle form or reversed form.
• The thermostatic head with our incompressible liquid-filled sensor guarantees a reliable and precise room temperature control.
