There are many smaller items when it comes to pneumatic products. We carry a ton of replacement valves, check valves, diaphragm valves, outlets and many other miscellaneous items. Our most popular inventory item is a pneumatic air valve actuator that is used on Barber Colman ball mills and Raymond mill. This is the most popular item we have in stock since it is used on so many different equipment products and it is very hard to find in stock anywhere else.

The 30108 Valve Actuator is a pneumatic actuator that controls the valve to doors. The MK-6621 Valve Actuator has a working pressure range of 0-5 PSIG and a maximum reverse travel of 1-1/4". The maximum output flow rate is 10.3 cubic feet per hour per valve. This unit moves a hydraulic valve enough for one door to open or closes forcefully.

The MK-6621 is used as an actuator and control function to open/close a valve in response to a pressure signal. This valve operator is a pneumatic, normally closed type air actuator which houses an integrated pilot valve pneumatically connected to the positioner relay control motor through the positioner open channel. The operator operates at low PH differential and requires no pilot air supply.
