The COMAR valves are compact 2- and 3-way control valves with male thread connection or flange. For the male thread there are normal and welded fittings. The inner trim is made of high quality stainless steel and together with the sealing materials and the packing gland guarantees maintenance free reliable long term operation. The valve characteristic is optimized for thermodynamic processes. This makes these valves very suitable for precise control in heating, air-conditioning and cooling systems. The extremely low leakage rate in the closed state and the control characteristics minimize energy losses in the respective system.
