THE HUMPHREY DIAPHRAGM-POPPET VALVE: HOW IT WORKS
BASIC 3-WAY VALVE
At rest (unactuated), media to SUPPLY port (1) fills the bottom cavity and underside of the bottom diaphragm, causing its poppet to seat and seal tight. The valve will not leak.
Upon actuation (actuated), significantly greater force applied over the top diaphragm causes the valve to shift instantaneously, opening the flow path from SUPPLY port (1) to COMMON port (2). The top poppet seats and seals tight, closing the path to EXHAUST port (3). This is a frictionless design, with high shifting forces resulting in valves that cycle reliably every time and valves that “Cannot Stick. Will Not Leak.”
Releasing the valve actuation pilot pressure permits the bottom diaphragm to quickly shift closed from SUPPLY port (1). Any downstream pressure present at the COMMON port (2) instantly becomes present under the top diaphragm (RED), accelerating the position shift, creating the valve’s “Quick Dump” feature to EXHAUST port (3).
2-WAY VALVE
This Diaphragm-Poppet design provides an excellent, leak-free, 2-way valve function with the EXHAUST port (3) plugged.
When the valve closes, any residual downstream pressure becomes present under the top diaphragm (RED), assisting with an accelerated closing, while the bottom poppet seals tight into its bottom seat.
Humphrey’s B Series Air Pilot Solenoid 2- and 3-way Valve Series is a modernized alternative to our original diaphragm-poppet product line. With interchangeable piping and mounting, the “Cannot Stick. Will Not Leak” advantages of the classic valve design have been continued and now feature a modernized DIN-style solenoid operator that reduces overall size and cost for our customers.
Three types are offered:
- The internal pilot pneumatic type is high flow and rugged, ready for reliable control even with poor air.
- The brass body external air pilot type is designed for reliable control of low-pressure air and mild fluids.
- The external air pilot vacuum valve uses the vacuum pressure to seal tight.

INTERNAL AIR PILOT SOLENOID
These rugged 2- or 3-port valves outlast similar pneumatic solenoid valves in difficult and challenging factory applications. Suitable for clean or poor compressed air and clean or dirty ambient environments. The valve’s simple construction has few parts, no sliding seals, or any metal-to-metal contact. It shifts reliably and seals tight.
Models: B250E1, B500E1, B590E1
Media: Compressed Air, Inert Gases
Pressure: 30-125 PSI
Wetted Materials: Zinc Diecast or Aluminum, SST, NBR
EXTERNAL AIR PILOT SOLENOID
These high flow 2- or 3-port valves use an external air pilot source to reliably control low-pressure compressed air, inert gases, or even mild liquids in specialty and process control applications. Brass body is standard equipment. Works with the force of the pressurized media to reliably shift and seal tight.
Models: B250AE1, B500AE1, B590AE1
Media: Compressed Air, Inert Gases, Mild Liquids
Pressure: 0-100 PSI (Pilot: 30 PSI min.)
Wetted Materials: Brass, SST, NBR
EXTERNAL AIR PILOT SOLENOID | VACUUM
These high flow 2- or 3-port valves use an external air pilot source to reliably control vacuum. The greater the vacuum, the tighter the valve will seal. Ideal for dry, humid, and dirty vacuum systems. Fluorocarbon diaphragms are standard. Large venting port dumps vacuum quickly. No lubrication required. No sticking. Outperforms all others.
Models: VAB250AE1, VAB500AE1, VAB590AE1
Media: Vacuum
Pressure: 0-29.5” Hg (Pilot: 30 PSI min.)
Wetted Materials: Zinc Diecast or Aluminum, FKM
