IVAR OPTIMA - Аксессуар для системы HVAC

In the OPTIMA series of thermostatic valves, functionality meets aesthetics, thanks to a group of valves with a special design that suits the decor of any environment.‎ The variety of versions available (black, gold, silver, white, chrome and stainless steel) make it a perfect addition to heated towel rails or radiators in the same colour, guaranteeing an elegant match.‎ OPTIMA thermostatically operated valves are equipped with a flow limiter device which is a double regulation system that, through a hole selector calibrated in six positions, determines the maximum supply to the heating element.‎ The selector allows for the regulation of flow through the valve from Kv = 0.‎1 to Kv = 0.‎6.‎ All of the thermostatic inserts can be inspected and the o-ring seal of the stainless steel spindle can be substituted, if necessary, while the system is working.‎ OPTIMA valves are supplied with a 3/4'' F rotating connection and 3/4'' M - 1/2'' F nipple to allow a perfect connection with all types of radiators.‎ The H valves are suitable to floor or wall connection and represent a comfortable alternative to a lockshield-valve kit.‎ The thermostatic head DH 01 is the natural completion of OPTIMA valves, with a response time of just 10 minutes that allowed the head to obtain class A in prestigious TELL labelling system.‎ Technical features Valves Max working temperature: 100 °C Max working pressure: 10 bar Max differential pressure: 1 bar Thermostatic head Liquid expansion thermostat Setting range: 6.‎5÷28 °C Hysteresis: 0.‎5 K Response time (Z): 10 min Water temperature effect (W): 0.‎8 K Heat element inalterability range: -15÷+60 °C Max heat transfer fluid temperature: 100 °C Possibility of limiting and blocking the setting Materials Valves Brass parts: EN 12165 CW617N Spindle: AISI 316L Protection cap: ABS Flow rate selector: PPA Sealing components: peroxide EPDM Thermostatic head Knob: CW508L brass Other brass parts: EN 12165 CW617N Regulation spindle: C72 steel Head body and locking pin: ABS Safety device: cartridge and spindle: POM pring: spring steel wire DIN 17223 class D Further info from manufacturer on OPTIMA IVAR
