Diaphragm Valves - Spartan Scientific

Diaphragm Process Valve, 2-way, 2-position, Normally Closed

The Spartan Scientific Series 35G5 2-Way, 2-Position all stainless-steel solenoid diaphragm valve offers the highest flow for the smallest size in the industry, with the 316 stainless steel body and bonnet. The valve is designed from the ground up using modern design technologies and materials. Featuring a full flow 1/2” (12.5 mm) orifice, available in Normally Closed configurations. The rugged stainless body is media compatible, robust, and is designed to meet rigorous flow requirement up to 29 GPM @ 150 PSI water. The body is available in 1/4”, 3/8” and 1/2” NPT, and the low wattage solenoid features a DIN Style “A” EN175301-803 (Formerly DIN 43650) electrical interface and is nylon encapsulated. FKM, NBR and EPDM are standard elastomers, and the operators are made of stainless steel with copper shading rings for AC versions. Typical applications include control of inert gases, water, and compatible fluids.

The Spartan Scientific Series 3680 2-Way, 2-Position solenoid diaphragm valve offers the highest flow for the smallest overall size in its class. The valve is designed from the ground up using modern design technologies and materials. Featuring a full flow orifice, the 3680 is available in either Normally Closed or Normally Open configurations. The PEI 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 3/4” and 1” NPT. The low wattage solenoid features an Industry Standard 22 mm wide coil electrical interface and is nylon encapsulated. FKM, EPDM and NBR 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.

Diaphragm Process Valve, 2-Way, 2-Position, Normally Open, Brass Valve Body

The Spartan Scientific Series 3505 is a 2-Way, 2-Position, internally piloted solenoid valve for the control of air, emulsion, inert gases and water. The valve features an all brass body and a full flow 1/2” orifice while maintaining a 1.5 minimum pressure differential. The design allows for a tight seal on the orifice at 0 psi. 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 activation (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, internally piloted solenoid 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 gives full flow throughout the pressure range starting with a Maximum Operating Pressure Differential of 1.5 psi while remaining sealed at 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 Style “A” EN175301-803 (Formerly DIN 43650) 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 3516 2-Way, 2-Position Normally Closed or Normally Opened solenoid diaphragm process valve offers the highest flow for the smallest overall size in its class as compared to competitive units. The valve is designed from the ground up using modern design technologies and materials. The potable water brass body is media compatible, rugged and virtually indestructible. The body is available in 1/4”, 3/8” and 1/2” NPT. The low wattage solenoid features a DIN Style “A” EN175301-803 (Formerly DIN 43650) electrical interface and is nylon encapsulated. FKM, EPDM and NBR are standard elastomers and the operators are made of stainless steel / brass or stainless steel / brass with copper shading rings for AC versions.
