The Spartan Scientific Series APVS04 is an inert gas/spring operated, Single Acting Normally Closed, or Double Acting media compatible diaphragm valve, designed for control of high purity, aggressive and corrosive liquid chemical media. It has a miniature overall footprint, and low dead volume. The Series APVS04 features media compatible composite body, and FKM, NBR, and EPDM elastomers to control the 6mm orifice which afford Cv ratings of .72 that far exceed competitive valves of this type and size. Media pressure ratings range from 0 to 200 psi and pilot pressure is 60 psi minimum. A Normally Open version can be made using a Normally Open pilot valve. In the case of pilot gas failure, the valve will fail closed. In the case where electric power is lost but pilot gas remains, the valve will remain open. Each valve is tested to bubble tight standard ANSI FCI 70-2 Class VI. The Series APVS04 can be controlled by our proven Spartan Scientific 3-way solenoid pilot valve which enhances operation with manual override and indicator lighted connector options, and is used where sampling, draining, or transferring process fluid are performed. An optional magnetic piston is available for end of stroke sensing when combined with the additional valve position sensor.

The Spartan Scientific Series APVS08 is an inert gas/spring operated, 2-Way 2-Position Normally Closed (fail safe), Normally Open or Double Acting media compatible diaphragm valve designed for control of high purity, aggressive and corrosive liquid chemical media. With a small overall footprint, and low dead volume, the Series APVS08 features CPVC bodies, and FKM, NBR, EDPM and PTFE diaphragms to control orifice size of 16mm which afford Cv ratings of 4.70 that far exceed competitive valves of this type. Pressure ratings go from 0 to 120 psi and each valve is tested to bubble tight standard ANSI FCI 70-2 Class VI. The Series APVS08 can be controlled by our proven Spartan Scientific 3-way solenoid pilot valve which enhances operation with manual override and indicator lighted connector options. The Normally Closed version features an optical position indicator showing valve open condition. The Series APVS08 is used where sampling, draining, or transferring process fluid are performed. The Normally Open version function is accomplished by use of a Normally Open solenoid pilot valve. Upon loss of power, namely pilot gas, there is an internal spring that will fail closed in the spring closed version. If this is not a pre-ferred condition, Normally Open fail can be accomplished using a Double Acting version and a 4-way valve plumbed to open on spring return, creating a full Normally Open fail mode. An optional magnetic piston is available for end of stroke sensing when combined with the optional valve position sensor.
