Operation
The BERMAD Model FP 405-02 is a simply designed,
manually operated, on/off valve. It is particularly suited for
industrial hydrants.
The valve is held closed when line pressure is applied to
the control chamber. Sealing is drip tight keeping the
downstream piping dry.
To open, pressure is manually released from the control
chamber by a 1/4turn of the Manual Release Pilot handle.

Engineer Specifications
■The valve shall be a line pressure driven, elastomeric type globe valve with a rolling-diaphragm.
■Valve actuation shall be accomplished by a fully peripherally supported, one-piece balanced rolling-diaphragm,
vulcanized with a rugged radial seal disk. The diaphragm assembly shall be the only moving part.
■The valve shall have an unobstructed flow path, with no stem guide or supporting ribs.
■The valve cover shall be removable for in-line service, enabling all necessary inspection and servicing.
■The manual release pilot valve shall be supplied as an assembly with the main valve. It shall require only 1/4turn for
full opening or closing. It shall be equipped with a device to regulate the opening speed.
■The valve trim shall be supplied as an assembly, pre-assembled and hydraulically tested at an ISO 9000 & 9001
certified factory.
Notes:
1. L1 & La1 are for flanged ANSI
#125 / #150 and ISO PN16.
2. L2 & La2 are for threaded female,
NPT or BSP.
3. Data is for maximum envelope
dimensions, component
positioning may vary.
4. Provide adequate space around
