BCV1 and BCV20 Blowdown Valves
Description The BCV1 and BCV20 valves are small bore, normally closed valves with a brass body and corrosion resistant internal components. They are primarily intended for low and medium pressure boiler blowdown applications. BCV1 and BCV20 valves are identical apart from the orifice size, the BCV1 having a 3 mm ( 1/8 ") orifice and the BCV20 a 6 mm ( ¼ ") orifice. Valves are supplied complete with a mains connector, which is protected to IP65 and is suitable for 3 x 1 mm ² (18 AWG) cable. Available sizes and pipe connections
