boiler drainvalve 3/4

Valve suitable for interrupting fluids that are generally non-corrosive, compatibly with the valve materials. Plumbing and heating systems are the ideal fields of application, where this valve is used to unload heat transfer fluids from the heating system. It’s a reduced bore valve and the ball seal is guaranteed by two PTFE seats. The operating mechanism seal features two O-Rings with an internally installed stem and anti-ejection system. It is advisable to carry out a complete maneuver cycle at least once every three months in order to prevent limescale deposits that could compromise the valve functioning.

The Snow Melting Control 654 is designed to operate electric or hydronic equipment to melt snow or ice from any surface including driveways, walkways, patios, business entrances, parking ramps, loading docks, hospital entrances, helipads or car wash bays. The surface temperature for snow melting is controlled automatically to reduce operating energy costs. The 654 has an automatic start and stop function when used with the Snow/Ice Sensor 090 or 094. Automatic start with a timed stop is available when used with the Snow Sensor 095. The 654 can operate a dedicated hydronic boiler or a mixing device. Isolation relays are required to operate line voltage pumps. Electric systems require a separate GFCI and electrical relay contactor.
