2-WAY NORMALLY OPEN

A complete line of valves with a great selection of options and exceptional proven performance. The standard in the field. Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials.

The flagship valve initially created for fluid power industry.
Heavy duty and made of stainless steel.
A real workhorse with proven performance.
It has the greatest amount of options available of all the valves.
Wide range of orifice sizes from 1/32" to 1/8".

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (21J9ZGM 120/60) repair pack (K21JDX AC)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (O21JDDGM 120/60)

Operating Conditions:

Media:

Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials. (Series 20 pressure ratings may change due to the viscosity of the liquid.)*
