Spartan Scientific | Air Piloted Valves

Air Piloted Valves

Spartan Air piloted valves are offered in sizes from 1/4″ to 2″ NPT and control media and steam from 1 to 750 psi in various valve configurations. These rugged process valves are used in rigorous environments where precise control of media is required. All versions incorporate a long life air actuator which provides the control of piston and ball valve type valves. Materials include brass, bronze, and stainless steel. These valves are media separated by means of the pneumatic actuators as valve operators.

Product Lineup

Series APVS04 – Media Separated Air Piloted Valves

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.

Series APVS06 – Media Separated Air Piloted Valves

The Spartan Scientific Series APVS06 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 APVS06 features media compatible composite body, and FKM, NBR, and EPDM elastomers to control the 1/2” orifice which afford Cv ratings of 2.45 that far exceed competitive valves of this type and size. Media pressure ratings range from Vacuum to 150 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 APVS06 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.

Series APVS08 – Media Separated Air Piloted Valves

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.

Series APVS15 – Media Separated Air Piloted Valves

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. The Normally Closed version features an optical position indicator showing valve open condition. The APVS15 is used where sampling, drain-ing, or transferring 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. An optional magnetic piston is available for end of stroke sensing when combined with the optional valve position sensor.

Series APV-23 Air Piloted Valves

The Spartan Scientific Series APV-23 is 2-way, 2-position valve specifically designed for the control of air, oil or steam The Series APV-23 uses a specially designed Teflon Chevron® seal which ensures separation of the media and pilot sections. In the single acting Normally Closed version, the Series APV-23 uses a spring extended pneumatic operator connected to a sealing disc which when retracted unseats from a precision orifice and allows fluid flow. When pilot pressure is removed from the Series APV-23 the seat returns to the orifice and flow stops. Features of the Series APV-23 are the ON-OFF indicator at the top of the pneumatic actuator and can be used for high temperature liquids compatible with the materials of construction and steam. The stainless steel body is standard and is available in sizes ranging from 1/2” to 2.0” NPT and can control media up to 215 psi in various configurations.

Standard sealing materials include FKM, NBR or PTFE. The bronze valve body is available in 1/2 “ to 2.0” NPT port sizes in various versions. The valve is offered with single acting Normally Open, Normally Closed, remote air pilot, or double acting pilot operation. Operating pressure ranges from 0 to 190 psi with maximum pilot pressures of 80 psi dependent upon function. Soft shifting can be obtained by the use of flow controls on the pilot ports. Typical applications for the APV-10 are media control of solvents, water, water with suspended particles, and coolants.
