Proportional pressure control valve

Nominal diameter 2

Air piloted seat valve

 

_ Air piloted proportional pressure valve

_ Reliable, rugged design

_ Excellent accuracy

_ IP 65 environmental protection in normal position

Medium:

Oil free, dry air, filtered to 5 μm

Output pressure:

0,2�?,0 bar, 0,2�?,0 bar, 0,2�? bar (2 wire version)

0,14�?,0 bar, 0,14�? bar (3 wire version)

Flow capacity: Up to 300 Nl/min

Air consumption:

<4 bar: 0,85 l/min typical

>4 bar: 1,75 l/min typical

Operating pressure:

At least 0,7 bar above maximum required output pressure

Connections: G1/4

Operating temperature range: -20 to +70 °C

Response time:

<2 bar: less than 0,5 s for 10 �?90% step change

>2 bar: 2 s for 10 �?90% step change

Total error:

±0,5 % of span (typical, indepentdent error includes the combined effect of non-linearity, hysteresis, deadzone and repeatability)

Temperature effect:

Typically 0,1 % of span / °C for span and zero over operating range

Supply sensitivity:

> 0,025 % span output change per % supply pressure change

Failure mode:

Signal falls to bleed pressure when electrical supply fails

Mounting:

Integral surface mounting bracket provided for referred vertical mounting. 50 mm pipe mounting kit available.

Material:

Zinc die-casting passivated and epoxy paint, nitrile diaphragms, stainless steel/nylon flapper nozzle and supply valve

Weight:

1500 g approx.
