Control valves (cont.) 20 Solutions Q&A 6.2 Excelon valves ? 6.2.1 What versions are available? The individual valves for use in Excelon 74 are 2/2 and 3/2 poppet valves P74A and P74B. There is a 2/2 soft start (P74E) and 3/2 on-off valves with solenoid or pilot operator (P74C). The 3/2 valves have optional lockout slides. ? 6.2.2 Are the Excelon valves direct ported? The valves in the Excelon 74 range are intended for modular installation only. If you need a threaded inlet/outlet use a Quikclamp and pipe adapter. 6.3 Shut off valves ? 6.3.1 What options are available? The Olympian 1" product line has a ball valve (T68), but recent products have moved to the slide type. They are generally available in 2/2 (non-exhausting) and 3/2 types, for use upstream or optionally downstream of FRL units. ? 6.3.2 Can they be locked? All the slide valves in Excelon and Olympian Plus can be locked closed using the padlock hole provided in the blade. For certain applications where it is vital that the air is not turned off, a lock open and closed option is possible (eg T64A or T64C). The T68 can be locked by dropping in the lock ring and fitting a padlock. ? 6.3.3 Why are the blades different colors? The color of the slide depends on the valve function and the market in which it is sold. Yellow = 3/2 exhaust not tapped OSHA (USA) Black = 2/2 Excelon 74 Red = 3/2 exhaust tapped (Europe) ? 6.3.4 Do we have downstream shut off valves? Yes. The Excelon valves can be used either upstream or downstream, and will always vent the downstream system. In Olympian Plus you need to use a special downstream version. ? 6.3.5 Is there a shut off which fits between yokes in Olympian Plus? Yes. This can be used within a build, or in duplex assemblies. ? 6.3.6 Can I use an upstream shut off downstream? The Excelon family valves can be used either upstream or downstream. If used downstream, remember that the FRL units remain pressurized - the valve vents the downstream system. There are special versions of the Olympian Plus and 68 Series valves for downstream use.
