| Accessories to Valve Positioners |
Did you know that VAC offers a pneumatic lock up valve and stand alone I/Ps? Currently we are stocking a double acting pneumatic lock up (pictured below on the left) where the customer requires a fail in last position upon loss of air supply. We sometimes think that loss of air supply simply means a cut tube, but it can also mean a slow bleed of supply which could cause the valve to go to the 4 mA position, and not the failure point. To find out more about the pneumatic lock up click HERE to read more.
Stand Alone I/Ps are still widely used in several different applications in our market. They can be used because the vibration on the valve is too much for electronics to handle and because of bad plant air. Keeping them in a cabinet with good filtration eliminates the possibilities of failures due to bad plant air. I/Ps can be used on diaphragm valves that use a 3 to 15 psi or 6 to 30 psi, or to positioners to modulate the valve. Pictured is an Explosion proof stand alone I/P with mounting hardware.
