Diaphragm Valve Vacuum Valves
from Plast-O-Matic Valves, Inc.
Series VB/VBM Patented diaphragm design assures dependable, repetitive, bubble-tight sealing to protect enclosed tanks from collapse or structural damage during draining. Also eliminates siphoning of dangerous fluids,and prevents vacuum damage to sensitive instruments and filters. 1/2 ″, 3/4... [See More]
- Type: Diamphragm

- Port OD: 0.7500
- Port Flange & Seal Type: EPDM, FKM
from Equilibar, LLC.
Equilibar electronic vacuum regulators are available in 1/4 to 4 inch sizes to handle all flow rates. The innovative design has more than 5X the flow stability of traditional spring regulators. That means that your vacuum process can remain stable even as gas flow rate changes over wide ranges. [See More]
- Type: Inline; Diamphragm
- Vacuum / Pressure Range: Low or roughing vacuum level (> 1 torr)
- Port OD: 0.2500 to 4
- Temperature Range: 608
from Edwards Vacuum
Edwards SP Speedivalves are diaphragm sealed in-line, isolation valves. The construction consists essentially of a flexible elastomer dia phragm which is sealed onto a lightly polished seat by a screw thread mechanism. The mechanism is isolated from the system by the diaphragm resulting in an... [See More]

- Vacuum / Pressure Range: Elevated or positive pressures (>> 760 torr)
- ISO Port Flange Size: NW 10
- Temperature Range: 32 to 104
from VACUUBRAND, Inc.
VM series valves are hand-operated diaphragm valves. They are used as isolation valves, air-admittance valves or manual-control valves. Depending on the rotation of the wheel, the valve is open more or less. The gas-contacting parts are made of materials such as stainless steel and PTFE, which offer... [See More]
- Type: Inline; Diamphragm; Straight Through
- ISO Port Flange Size: NW 16
- Port OD: 0.6299
- Leak Rate: 1.00E-4
from VAT, Inc.
Manually operated diaphragm valves with forged body and robust actuator. Features. Diaphragm made of FKM (VITON). Easy replacement of the diaphragm [See More]
