News: A Super control valve for small diameters

TECHNICAL DATA

All M1 series CV / KV factors are significantly higher than what is known to the market.
Therefor when relating to sizes an M1 valve size can apply to a larger line size than its own.
Sizes: 4"-6" dia.
3" and 8" valves are in the process of development.

Valves can be supplied with different inlet and outlet sizes.

Materials

Part	Material
Valve bodies, pistons, bushings, front and rear plugs	Reinforced fiber-glass nylon
Main seal	N.B.R rubber, Shore index: 80
O-rings	N.B.R rubber, Shore index: 70
Clamps, bolts, inserts	Stainless steel 316
Metal envelope (for high pressure)	Spheroid iron with polyester coating

Can be supplied with different structural materials for various applications

Working Pressure Range
1. When the line pressure serves for activation:

Maximum pressures:

Plastic model for pressures of up to 220 psi / 16 bar.

Plastic metal-coated model for pressures of up to 360 psi / 25 bar.

Minimum pressures:

Model	Closure PSI	Meters	Opening Psi	Meters	Full opening Psi	meters
N.O	19	13	3	2	4	3
N.O with spring	7	5	3	2	9	6
N.C	28	20	3	2	10	7
N.C with spring	4	3	4	3	28	20

The closure pressure can be reduced at the expense of the opening pressure.

2. External Control Pressure

Plastic model for vacuum condition and pressures of up to 220 psi / 16 bar.

Plastic metal-coated model for vacuum condition and pressures of up to 360 psi / 25 bar.

Booster pressure
N.O model also closes when the control pressure is 85% of line pressure.
N.C model also opens fully when the control pressure is 80% of the line pressure (opening begins at 25%).

Temperature range
Water temperatures of up to 140^F / 60^C.

Couplings

Quikcoup 4" and 6" (Groove system).

Quikcoup-Flange couplings complying with ISO and ANSI Standards can be supplied

for connecting to flanges.

Flow rate factor calculated by following equation:

Where:
Kv - flow factor (m³/hr at head loss of bar)
Cv - flow factor (GPM at head loss of 1.0 psi)
Q - Flow rate (m³/hr, GPM)
dp - Head loss (bar, psi)
S - Specific gravity of fluid (for water, S = 1 gr3/cm3)

Kv = 0.856 CV
