Air Piloted Solenoid 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.
The Spartan Scientific Series APV-10 is a versatile 2-way, 2-position air piloted valve that can be controlled by a three-way, four- way solenoid valve or hand pilot valve. The APV-10 features a reciprocating piston operator which is media separated and controls air, fluids, fluid emulsions, water, or any media compatible with the valve body materials. Standard sealing materials include Buna, Viton or PTFE. The bronze valve body is available in 1/2 " to 2" 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 235 psi with pilot pressures of 30 to 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. Also available is a three way solenoid pilot valve (Spartan Series 3823), which may be added to operate the APV-10.
The Spartan Scientific Series APV-20 is a 2-way, 2-position valve specifically designed for the control of steam. The APV-20 uses a specially designed Teflon Chevron® seal which ensures separation of the media and pilot sections. In the single acting normally closed version, the APV-20 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, the APV-20 seat returns to the orifice and flow stops. A feature of the APV-20 is the ON-OFF indicator at the top of the pneumatic actuator. The APV-20 can be used for high temperature liquids compatible with the materials of construction and steam. The bronze body is standard and is available in sizes ranging from 1/2" to 2" NPT and can control media up to 300 psi. Also available is a three way solenoid pilot valve (Spartan Series 3823), which may be added to operate the APV-20. Consult factory for details
The Spartan Scientific Series APV-30 is a rugged full featured, pneumatically piloted ball valve. The unit is available in normally open, normally closed or double acting versions. With sizes from 1/2" to 2" NPT or BSP, the APV-30 will flow up to 85 gpm. The unit is compact as compared to competitive rack and pinion or motorized ball valves and comes standard with an ON-OFF indicator. The APV-30 features PTFE ball valve sealing using Chrome plated Brass or 316 Stainless balls. The valve body materials are Nickel plated Brass and 316 Stainless. Also available is a three way solenoid pilot valve, (Spartan Series 3823) which may be added to operate the APV-30.
