The Spartan Scientific Series 3505 is a 2-Way, 2-Position, Normally Closed valve for the control of air, emulsion, inert gases and water. The valve features an all brass body and a 0 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). 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.
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. 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 aMaximum Operating Pressure Differential of 0 psi. The body is available in 1/4″, 3/8″ and 1/2″ NPT sizes and features a stainless steel anti-flex ring for port strength. 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, emulsion, inert gases, oil and water control, condensate drainage, hot water plumbing and sprinkler systems.
The Spartan Scientific Series 3580 is an engineered composite 2-Way, 2-Position solenoid/air operated valve designed for the control of liquid media and inert gas. The valve exhibits a large 1/2” orifice and three port sizes standard, 1/4″, 3/8” and 1/2” NPT. The Normally Open version of the 3580 has a unique operator that allows for function without the use of a bypass tube as with the 3510 and has a push non-locking and a turn-lock manual override. There is no override available on the Normally Closed version of this valve. The valve’s compact design utilizes the latest in material sciences with the use of composite materials in the valve body. The solenoid pilot is power saving low wattage, made of stainless steel working components and is miniaturized to fit in tight places. Standard elastomers available are FKM, NBR, and EPDM. The fully encapsulated coils are available in all standard voltages and with spaded, flying leads or with a connector attached. Typical applications are for installations where there is a need to control inert fluids and gases, condensate drainage, hot water plumbing and sprinkler systems.
The Spartan Scientific Series 3585 2-Way, 2-Position solenoid diaphragm valve offers the highest flow for the lightest weight in its class. The valve is designed from the ground up using modern design technologies and materials. Featuring a full flow 1/2” (12.5 mm) orifice, the 3585 is available in either Normally Closed or Normally Open configurations. The nylon body is media compatible, light in weight, and by use of external metal port rings, is virtually indestructible. The Normally Open version of the valve features an optional turn lock manual override and has no external by-pass tube which eliminates leak points and size. The body is available in 1/4”, 3/8” and 1/2” NPT or BSP. The low wattage solenoid features a DIN 43650 Form A electrical interface and is nylon encapsulated. FKM, NBR and EPDM are standard elastomers and the operators are made of stainless steel / brass or stainless steel / brass with copper shading rings for AC versions. Typical applications include control of inert gases, water and compatible fluids.
The Spartan Scientific Series 35KR 2-Way, 2-Position solenoid valve is a variation on the popular Series 3500 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 0 to 150 PSI in the all 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.
