The 4-way PEEK bulkhead switching valves offer several flow configurations and are ideal for small sample volume injection applications. It is made of PEEK that offers excellent chemical resistance. It has 1/4-28 ports and 1/16'' OD tubing.   It is available in diagonal flow, right angle "L" and single T flow. Tefzel 1/4-28'' nuts and plug come with the valve. 

Key Features

• 4 positions with L Configuration
• Max operating pressure: 500 PSIG (34 bar)
• Maximum operating temperature: 80 C (176F)
• Through-hole diameter: 0.040'' (1.0mm)
• Port to port volume: 6.2uL

Typical Applications

• The Right angle flow-switching valve ("L") is a 2-way selection valve, appropriate for detector or column switching applications. 
• The 3-way flow-switching valve ("T") is an appropriate choice for applications that requires a tee connector that can also e used as a 2-way selection valve.
• The 4-way diagonal flow-switching valve can be used for protecting sensitive components, such as column of an instrument during cleaning or passivation cycle.
