QUESTIONS 6.1 Soft start/dump valves ? 6.1.1 What sizes are available? We can do units in 1/4" through 11/2" actual port size, based on Excelon 72 (1/4 - 3/8), Olympian Plus 64 (1/4 - 3/4), Excelon 74 (3/8 - 3/4) or the new P68F (3/4 - 11/2"). ? 6.1.2 What operators are available? All valves have air pilot, 22mm solenoid and CNOMO solenoid options. In addition the P68F can use the Webber Excel 32mm solenoid. ? 6.1.3 Do we have an emergency dump? Yes. The P64F/P74F have an optional dump slide with a yellow handle, used to break the pilot signal and dump the downstream system. The slide can be locked out using a standard 8mm padlock or lockout hasp. The P68F has a dump handle as standard (optional without). Again this can be locked out. ? 6.1.4 How fast/slow can it go? The snap point where full pressure kicks in is fixed for a given line pressure. You can control the time between signalling the valve and the snap by using the needle valve adjuster. Refer to catalog sheet for minimum/maximum times, which will depend on the downstream system volume. ? 6.1.5 What is the minimum operating pressure? The snap action requires a minimum line pressure of 44 psig (3 bar). ? 6.1.6 Will the unit soft start only? The combined function valves are not intended for use as soft start only. If you need such a valve use the Excelon 74 individual valves. ? 6.1.7 Will the unit dump only? The combined function valves are not intended for use as dump only. If you need such a valve use the Excelon 74 individual valves. P64F P68F P74 Air Operated P72C P74 Lockout Valve
