- Bellows reliability MTTF; 130000 cycles
- Pressure range valve open: 1 x 10-9 to 2000 mbar
- Leak rate; < 1 x 10-9 mbar ls- 1
- Ambient operating temperature; 5 °C to 50 °C
Edwards PV40EKA Solenoid Isolation Valve, 110-127 V, Single Phase, 50/60 Hz, Aluminum, C41403000
Overview:
The Edwards PV40EK series valves are compact, light-weight electromagnetic vacuum valves suitable for use in vacuum pipeline systems down to 1 x 10-9 mbar. A double wound coil combined with an electronic switching circuit ensures low energy consumption, low operating temperatures and extended operating life.
Bellows sealed, the PV40EK solenoid operated valves are available with either aluminum or stainless steel bodies, and in right-angle (PVEK) and in-line (IPVEK) versions, with an overall MTTF of up to 130,000 cycles.
The valve mechanism consists of a solenoid operated moving pole with integral valve pad and bellows assembly. The moving pole is enclosed in an iron casing and the bellows assembly is housed in the lower vacuum body, thus isolating the valve mechanism from the system.
The body terminates in two KF flanged ports and valve pad sealing is by a fluoroelastomer O ring seal. A plastic control box houses the electronic switching and rectification circuit which is protected by a surge proof fuse; a magnetic reed change-over switch provides the switching facility and can be wired for remote indication of valve open/closed position. The switch terminals and mains electrical terminals are also located in the control box.
Improved circuit board design has achieved enhanced life expectancy up to 5 times that of the previous design. Overall MTTF for the valves is up to 500,000 cycles. The valves are provided with separate plug and socket connections rated at IP65 and comply with IBM electrical standards.
Features:
- Transient high power for opening - electronically switched
- Low energy consumption in teh 'hold open' position
- Enclosure rating to IP55
- Grease free vacuum
- MTTF up to 130000 cycles
- Circuit protected against transient low voltages
- Improved circuit board reliability
- User friendly plug and socket connections to IP65
