Diaphragm Process Valves

Spartan Scientific produces a full line of diaphragm process valves which incorporate the state of the art solenoid, premium materials made to exacting specifications and quality standards. Spartan diaphragm valves offer a port range from 1/8″ to 2″ NPT, BSPT, as well as manifold mounting styles. This unique and targeted style of valving was produced to fill the demanding needs of Spartan’s customers. Materials used are brass, stainless steel as well as engineered polymers for value and long trouble free service. These full flow, low cost valves are in use in many various applications from mobile to industrial, garbage trucks to potato chip manufacturing.

  • Series 3500

    The Spartan Scientific Series 3500 2-way, 2-position solenoid/air operated pilot valve uses the latest combinations of technologies for materials and function. This combination provides the user with the highest quality, smallest size per Cv of flow and most competitive pricing of any valve on the market. The 3500 utilizes the latest injection molding and forging technologies available which garner the highest quality yields of components. When coupled with the Spartan 3800 series solenoid operator, and used as a direct acting/pilot operated valve, the 3500 gives full flow throughout the pressure range starting with an MOPD of zero psi. The forged body section gives strength and robustness to the valve, and is available in 1/4", 3/8" and 1/2" NPT sizes. The molded pilot section features a push, non-locking manual override, high cycle life solenoid parts and quick connect DIN 43650 "A" or "flying lead" electrical connection options. Typical applications include air control, inert gas control, water, inert fluids, condensate drainage, hot water plumbing and sprinkler systems.

  • Series 3505

    The Spartan Scientific Series 3505 is a 2-way, 2-position, normally closed or normally open valve for the control of air, oil, water, or media that is compatible with valve materials of manufacture. The valve features a zero minimum pressure differential while still boasting a full flow 1/2" orifice. Available in 1/4", 3/8" and 1/2" NPT, the 3505 can handle pressures to 230 psi. The encapsulated coil construction ensures that the valve functions well under long periods of energization (100% duty), as well as providing a high degree of environmental protection (NEMA 4) when used with a Spartan Connector or in flying lead version. The inner valve functions as a direct assist using a flat diaphragm and orifice plate. Pressure differentials shift the valve to full open or full closed. A push, non-locking manual override is standard.

  • Series 3510

    The Spartan Scientific Series 3510 2-way, 2-position solenoid/air operated pilot valve uses the latest technologies for materials and function. This combination provides the user with the highest quality, smallest size per Cv of flow and most competitive pricing of any valve on the market. The 3510 utilizes the latest injection molding technologies available which make the 3510 compatible with many fluids and other media. When coupled with the Spartan 3800 series solenoid operator, and used as a direct acting/pilot operated valve, the 3510 gives full flow throughout the pressure range starting with an MOPD of zero psi. The polymer body section is available in 1/4", 3/8" and 1/2" NPT sizes and features a stainless steel anti-flex ring for port strength. The orifice for all sizes is 12.5mm or 1/2". The molded pilot section features a push, non-locking manual override, high cycle life solenoid parts, and quick connect DIN 43650 "A" or "flying lead" electrical connection options. Typical applications include air control, inert gas control, water, condensate drainage, hot water plumbing and sprinkler systems.

  • Series 35KR

    The Spartan Scientific Series 35KR 2-way, 2-position solenoid valve is a variation on the popular 3500 Series valves which feature miniaturized size vs. flow rate while allowing the user to manifold multiple outlets with one inlet.  The 35KR design features the direct pilot design which controls zero to 150 PSI in the all plastic version and 0 to 230 in the Brass Plastic version.  The intermediate orifice plate design is the key to the 35KR in that it includes all the details of careful orifice design and creates a simple sealing pattern which can be mounted to integrated equipment and complex manifolds with simple mounting screws.  The mounting style reduces leak points and numbers of connections.  The 12mm orifice promotes full flow while the valve body, at only 1.5 inches wide, can be gang mounted to give impressively small envelope packages with many outputs.  The simple mounting pattern is shown under dimensional data and can be machined into many varied manifold configurations.

  • Series 4500

    The Series 4500 solenoid valves are designed specifically for high flow, high pressure applications. With orifice sizes of 8mm to 12mm and port sizes of 1/4", 3/8" or 1/2" NPT, the valve is offered with a manual override standard. The coil is a quick connect DIN 43650 Form A design and is encapsulated for environment resistance. Typical applications include condensation removal, car washes, autoclaves or irrigation control.

  • Series 4600

    The Series 4600 2-way solenoid valves are pilot operated and available in 3/4" and 1" sizes. Offered standard with an adjustable metering handle to restrict or manually shut off media flow. The valves can be controlled by either internal or external pilot allowing control of low pressure to high pressure applications. Media and pilot can be separated to extend life by keeping corrosive material out of pilot section.

  • Series 4700

    The Series 4700 solenoid valves are designed specifically for high flow, high pressure applications.  With orifices sizes of 20mm to 25mm and port sizes of 3/4" and 1.0" NPT, the valve is offered with a manual override standard.  The coil is a quick connect DIN 43650 Form "A" design and is encapsulated for environment resistance.  Typical applications include condensation removal, car washes, autoclaves or irrigation control.
