With our commitment to you an integral part of all of our operations, we have collated some of our most frequently asked questions for you:
What is different about pneumatic relays?
Pneumatic relays are attached to circuits that conduct compressed air rather than a flow of electrons. When the presence of compressed air is flowing through one circuit, the force of that energy opens up a switch and begins to flow into a second circuit. In both of these varieties though, as well as in any other types of a relay, there needs to be a sensor present so that the switching can occur.
What is the difference between NC and NO valves?
NC means 'normally closed’ and NO means 'normally open'.
What are BSP threads?
The British Standard Pipe (BSP) is a family of standard screw thread types that have been adopted internationally for interconnecting and sealing pipe ends by mating an external with an internal thread and has been adopted as a standard scale used in plumbing fittings.
What is the difference between a parallel and a taper thread?
Parallel threaded fittings seal on a washer between the fitting and the face of the component's port, whereas taper threaded fittings rely on a wedged fit and use sealant between the fitting and port.
What is the difference between 2/2 way and 3/2 way solenoid valves?
A 2/2 way valve has 2 ports. If the valve is open then the two ports are connected and fluid can flow between them if it is closed the ports are then isolated. A 3/2 way valve has 3 ports which connect one port to either of the two other ports which are normally a supply port and an exhaust port.
