| Poppet Valve FAQ's 1. Are different coils available on the smaller sized poppet valves? (Yes, but a special part number is required.) 2. Is the manual override held captive in place? (Yes, the solenoid stem itself locates and holds this brass manual override in place. There is a slot (or groove) on the manual override.) 3. Is there an option code for external piloting solenoid air valves? (The option code is 14A) 4. What are these valves best suited for? (These valves are particularly suitable for applications where high flow and cycle rates are required.) 5. Is a lower watt solenoid operator available? (Yes, for U1 solenoid stems a 2.5 watt is available.) 6. Is field conversion from internal to external pilot supply possible? (Yes, in certain cases. Please consult factory.) 7. What is considered bubble tight? (Bubble tight for the poppet valve is considered as .24 cc or better per minute.) 8. Is it possible to convert N.C. to N.O.? (No, it is not.) 9. What is the cycle life of the poppet valves? (Recent tests have recorded 9 million cycles.) 10. Are viton seals available with the poppet valve? (No, they are not available.) 11. Are poppet valves strictly used for air? (Inert gases can be used with these valves.) 12. Can the internally piloted vacuum valve operate in an "open" circuit? (No, as stated, 5.9" of Hg is the minimum required.) |
