Straight

Design

The premium manual valves consist of:

•Valve housing PN10, DN10 or DN15 with

•M22 x 1.5 external thread connection on inlet

•external thread connection with union-nut and radiator tailpiece on outlet

•Valve insert

•Handwheel

Materials

•Valve housing made of nickel-plated brass

•Valve insert made of brass with EPDM O-rings and soft seals and stainless steel spindle

•Protection cap made of grey plastic

•Union-nut and tailpiece made of nickel plated brass with EPDM O-ring

Application

The MARS Series is a thermostatic valve, supplied with a manual handwheel. Thermostatic radiator valves individually control room temperatures and thus save energy. MARS Series type thermostatic radiator valves have quiet operation and are fitted to the supply of radiators in 2-pipe systems with medium flow rates.

The MARS Series is supplied with a fully operational handwheel for manual operation of the valve. To convert the MARS Series to thermostatic operation the handwheel is replaced by a radiator thermostat, e.g. Honeywell Thera-4.

Features

•Supplied with fully operational manual handwheel

•Easily upgradable to thermostatic operation by simply replacing the handwheel with a radiator thermostat

•Universal insert with medium flow rate

•Standard M30 x 1.5 thermostat connection

•Connection to all types of pipework DN10 to DN15

•Quiet operation

•Tail piece with integrated O-ring

V300 - MARS SERIES PREMIUM MANUAL VALVE

Function

The orifice between valve seat and valve cartridge increases when the valve is opened by turning the handwheel anti-clock- wise. More heating water can flow into the radiator or heat exchanger and the room temperature rises.

The orifice between valve seat and valve cartridge decreases when the valve is closed by turning the handwheel clockwise and the supply of heating water into the radiator or heat exchanger is throttled. At the right limit stop the valve is closed except for a possible leakage rate.

Please Note:

•To avoid stone deposit and corrosion the composition of the medium should conform with VDI-Guideline 2035

•Additives have to be suitable for EPDM sealings

•System has to be flushed thoroughly before initial operation with all valves fully open

•Any complaints or costs resulting from non-compliance with above rules will not be accepted by Honeywell

•Please contact us if you should have any special requirements or needs
