SV83 3-way Direct Acting Solenoid Valves
3-Way direct Acting Solenoid Valve
Port Sizes: 1/8′′ or 1/4 ′′ NPT
Pressure: 0-200 PSIG
Configuration:
SV833 • Normally Closed
SV834 • Normally Open
SV836 • Universal

These compact 3-way directing acting solenoid valves are available in normally closed, normally open and universal operating modes. They are available with 1/8′′ or 1/4 ′′ NPT pipe connections. This design allows coil replacement without disturbing fluid connections. Valves can be panel mounted to isolate coil connections within an enclosure while fluid connections are located outside. For special applications, contact your Valcor customer service representative.
SV85 Multi-Purpose Solenoid Valve
Balanced Poppet, 3-Way, Normally Closed
Port Size: 1” NPT
Pressure: 0-625 PSIG
Configuration: Normally Closed

Valcor Scientific, a Division of Valcor Engineering, has designed and engineered rugged, reliable solenoid operated valves for more than 40 years.
The SV85 Model was specifically engineered for controlling steam, water, gas, oil and other fluids in a variety of industrial markets.
The SV85 is a 3-way, direct acting balanced poppet solenoid valve that can be used in diverter, normally open or normally closed configurations.
Its vertical, upright mounting orientation, allows for a fail-safe position in the event of power failure.
Because balanced poppet solenoid valves are direct acting (open and close independent of the operating pressure), they are uniquely de signed to require no minimum operating pressure. In addition, this design eliminates pilot pistons and pilot holes, which can stick or be come clogged.

SV97 Cryogenic Solenoid Valves
2-Way Solenoid Valves
Port Size: 1/8” or 1/4”NPT
Pressure: Up to 1000 PSIG
Configuration: Normally Closed

The SV-97 are poppet type valves with Heli-arc welded, stainless steel construction. This provides a superior external hermetic seal. The valves provide bubble-tight shutoff for use in gas and liquid service. For water and gas applications,the SV-97 uses a KEL-F poppet as the sealing medium. Consult the factory with application parameters for optimum seal choice.

Application:
The SV-97 are used to handle cryogenic liquids and gases, as well as high temperature fluids in chemical processing, instrumentation and sampling applications. This series is especially applicable to ′′welded in place′′ applications, as well as those where potential leak points need to be minimized.

Operation:
The SV-97 are 2-way, normally closed solenoid valves, energized to open and failsafe closed. They are direct acting poppet-type which require no minimum operating pressure, and are capable of handling temperatures ranging from -320°F to +250°F. Placement of the coil away from the body allows solenoid generated heat to be dissipated away from the fluid being handled. The valves are capable of vacuum service (please consult factory on such applications). Valves mount easily with two screws through mounting holes on standard, L-shaped brackets.

Electrical:
SV-97 valves have continuous duty epoxy molded coils with 10′′ Teflon leads per UL Class H. General purpose electrical housings with either pigtail lead wire exit, or 1/2′′ conduit hub are standard. Nema type 7, Class 1, Division 2, Group C & D, and Class 2, Group E F & G, Explosion Proof Housing is available upon request.

Features:

  • Direct Acting, Poppet Type Construction
  • All-Welded Stainless Steel Body Assembly
  • Bubble-Tight Shut Off
  • No Minimum Operating Pressure
  • Six Types of Fluid Connections
  • Nema 7 Exp. Proof Coil Housing Available
Modular Design Valve (A Series)
Orifice Sizes: 1/32 to 5/32
Maximum Operating Pressure Range: 50 to 1000 PSIG
Flow Rate: 0.019 to 0.300 Cv

Predyne aka Precision Dynamics A Series gives you a highly adaptable design for practically all applications requiring flow between Cv 0.019 and 0.300. This robust 2- or 3-way miniature solenoid utilizes a stainless steel body to resist corrosion for most acids, alkaline solutions, and harsh environments. The A Series can also be made with a brass body for a more cost effective solution. Available in numerous port configurations orifice sizes, and material combinations, the A Series is a highly flexible valve that fulfills the requirements for most applications.

A Series with a stainless steel body is often the first choice for:

  • Medical Equipment
  • Laboratory Equipment
  • Food Processing Equipment
A Series with a brass body is an excellent choice for:
  • Industrial Applications
  • Automotive
  • Water Transfer Systems
High Flow Valve (D Series)
Orifice Sizes: 3/64 to 3/8
Maximum Operating Pressure Range: 10 to 900 PSIG
Flow Rate: 0.045 to 0.880 Cv

For maximum flow in a miniature solenoid valve the Predyne aka Precision Dynamics D Series valves delivers a wide range of CV values and maximum operating pressures. The D Series is also available in multiple body materials, seal materials, coil constructions, voltages, and wattages. Proven to perform for millions of cycles without failure, the D valve as with the entire valve series is ideal for manifold configurations, sub-assemblies, and complete fluidic systems. The D Series is the largest in a progression A Series, B Series, and C Series of the highly flexible, modular design, (general purpose) valves.

The D Series is excellent for applications in:

  • Agriculture
  • Defense
  • Sterilization Equipment
  • Industrial Automation
