Series 20 Model 26

3-WAY MULTI-PURPOSE Valve

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 (26JJ9ZGM 120/60) repair pack (K26JJX 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 (O26JJDDGM 120/60)

PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.

The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.

Our sales department is ready to answer questions and to solve your valve needs. Please feel free to call, chat or email us.
