The Hauck Micro-Cam Oil Valve (MCOV) is designed to provide positive, accurate, graduated control of fuel liquid flow to any type of burner. Flow control may be either manual or automatic. A large indicator dial provides a greater range of individual precision settings. This valve is specifically engineered to handle small to large oil capacities. B and F valves are UL listed for assured quality.
The Hauck MCOV is intended for flow control; it is not designed to replace a shutoff valve. For tight shutoff, a ball type or solenoid shutoff valve must be provided in the fuel supply line. These valves will successfully and efficiently handle any grade of fuel oil, even heavy fuel oils when preheated to the proper viscosity and flow characteristics. Valves are specially designed to reduce erosion from oil particulates. Liquid propane valves are also available.
