VAP series is a compressed air operated high vacuum gate valve that was developed based on a wealth of technology and experience in the vacuum field.
The conductance when the disk is opened is large, which maximizes the pumping performance of the vacuum pump.
The conductance when the disk is opened is large, which maximizes the pumping performance of the vacuum pump.
Features
- O-ring shaft seals draw little air into valves.
- Simpler structure makes maintenance easy.
- Use of aluminum alloy enables more lightweight design.
- Use of link mechanism enables more compact design.
- Low vibrations
- Low cost
Applications
- Evacuation system lines on vacuum equipment

Note:
1. This specification uses SI measurement units.
Conversion to non-SI units is as follows: 1Pa=7.5×10-3Torr
2. Ensure that maximum differential pressure for valve OPEN/CLOSE operations is no more than 1000 Pa.
*1：a.Seal characteristic value in static state. Leak rate doesn't include O-ring permeation rate.br /> b.Air adhering to shaft may be drawn in during valve operation, increasing apparent leak rate.
*2：Three OPEN/CLOSE signals are available. When ordering products with contacts, specify signal type and OPEN or CLOSE.
