Spartan Scientific introduces APVS Air Operated, Media Separated Shut Off and Diverter Valves.
- Rugged built from compatible materials
- Bubble tight control of water, ultra-pure and waste water
- High flow with low pilot pressure
- Electronic valve position sensing for positive feedback
Series APVS08
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. In the normally closed version, the valve features an optical position indicator showing valve open condition. The Series APVS08 is used where sampling, draining, transferring, or diverting 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 preferred 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.
Series APVS15
The Spartan Scientific APVS15 is an inert gas/spring operated, single acting normally closed, or double acting media compatible dia-phragm valve designed for control of high purity, aggressive and corrosive liquid chemical media. With a small overall footprint, and low dead volume, the APVS 15 features CPVC bodies, and FKM, EDPM and NBR elastomers to control orifice sizes 16mm and 20mm which afford Cv ratings of 4.70 and 10.9 that far exceed competitive valves of this type. Pressure ratings go from 10 to 100 psi depending on orifice size and each valve is tested to bubble tight standard ANSI FCI 70-2 Class VI.
The APVS15 can be controlled by our proven Spartan Scientific 3-way solenoid pilot valve which enhances operation with manual override and indicator lighted connector options. In the normally closed version, the valve features an optical position indicator showing valve open condition. The APVS15 is used where sampling, draining, transferring, or diverting process fluid are performed. 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.
About Spartan Scientific
Spartan Scientific was formed in 1987 with a mission to redefine industrial solenoid valves and related products. We started with DIN quick connect solenoid coils, quick mounting solenoid operators and interchangeable coil versions. Spartan has effectively reduced installation costs and related setup while reducing retrofits and service times. Spartan solenoid valves incorporate fully encapsulated coils and the highest quality brass and stainless steel in every assembly. Our solenoid operators can be placed directly into your assembly for a neater, more compact end product which meets functional as well as aesthetic demands. Many of the products manufactured by Spartan Scientific are specials, or variations of standard products.
Spartan strives to meet tough challenges with innovative design. If you do not see a specific valve or accessory, please ask one of our sales consultants for additional information or the possibility of Spartan producing a special product for your application. We are known for our quality solenoid valve timers, electronic shut off valves, air compressor drain valves, condensate drain valves and water drain pump valves.
