The BCM-10 is Atlantic Valve’s answer to low pressure gas applications. This ⅜” Brass Low Pressure Gas Solenoid Valve is engineered with a high tension spring and NBR diaphragm which creates a reliable “air-tight” seal under low or no pressure with gaseous media.
This valve is made for lower pressures. The spring strength, increased stability of the NBR seal lend to this valves ability to create a airtight seal in the absence of media pressure, however, this decreases the maximum pressure rating as well. This valve is rated for zero pressure differential up to 60PSI of pressure. Similar to most diaphragm valves this only functions properly in one direction. Any backpressure or backflow will prevent the valve from working properly and should be avoided.
This valve is composed of Brass, Stainless Steel and NBR. Natural gas and propane are compatible with the brass body, nitrile rubber seal material and stainless steel springs and interal components of the valve. All of the wetted components offer chemical resistance against propane, natural gas, and inert gases. This valve is normally closed meaning it is closed without power being applied and snaps open instantly when power is applied to the coil. It is always recommended for the normally position to be the most utilized position to maximize your coil life. This valve can be used on fluids however due to the design this valve offers much lower flow than our traditional solenoid valves. The BCM-10 uses our 410 series coil. This coil is avialablke in the 5 most popular voltages, 12VDC, 24VDC, 24VAC, 110VAC and 220VAC. For the DC voltages the coils require 20 Watts of power, while for the AC voltages the coils require 20 VA of power. Both the AC and DC valve bodies are fit with shading rings which are only required for AC power to reduce humming and vibrations. This means if your power supply changes from DC to AC you would only need to replace the coil to match your new voltage, and not the entire valve. Coils can only be used with the voltage listed on the coil and have a +/-10% voltage range from the voltage listed. This coil is rated for continuous usage, meaning it can be energized for many hours. It should be kept in mind that the coil temperature does increase the longer it is used and will eventually reach maximum resistance and minimum current, operating the coil at maximum temperatures will decrease the lifespan. It is recommended to factor in a 30 minute off cycle for every 8 hours energized to allow the coil to cool. This coil should be installed where there is airflow available to reduce the ambient temperature around the coil.
