for 3/4" to 1-1/2" series) with a 3:1 safety factor.
For High Cycle Applications: See page 7
PRESSURE DROP: See Ordering Information Table, page 20.
For detailed differential pressure charts, see page 56.
ACCURACY: ±2% of full scale
REPEATABILITY: ±1%
REVERSE FLOW BY-PASS OPTION: Features a two-piece cone that responds
to flow in the primary flow direction in the same manner as the standard design.
Flow in the reverse direction causes the lower cone shuttle to shift, moving it below
the sharp-edged piston orifice, which allows the fluid to flow freely in the reverse direction.
