. Sensors & Controls Miniature and Subminiature Solenoid Valves Gems specializes in made-to-order fluidic systems, and a major segment of that activity includes the integration of miniature solenoid valves and manifold assemblies. Our miniature and subminiature solenoid valves are utilized in solutions that serve industries ranging from medical and biotech to automotive and industrial equipment. Gems solenoid valves are designed to your specifications for each unique application. Each series offers a broad range of construction/performance options to build an endless array of configurations—too many to list in this catalog. From custom coils and manifolds to exotic materials and flow characteristics, there is very little that we cannot accomplish. Whether pneumatic or liquid, cryogenic or high temperature, vacuum or high-pressure, we partner with you to identify, create, and produce the best possible fluidic solution. If at any time, you have a question or simply want to give us your requirements and have Gems Sensor and Controls design your valve or system, please contact us by phone at 800-378-1600 or email us at [email protected].

General Purpose Valves A broad range of 2- and 3-way solenoid valves in both miniature and subminiature sizes. A wide selection of configuration options allows easy customization to match specific application requirements. Isolation Valves Isolation diaphragms protect media and moving parts alike. Ideal for high-purity Cryogenic Valves These valves provide reliable service to (-196°C). Ideal for liquid Nitrogen and Visit www.GemsSensors.com for most current information.

INTRODUCTION 4 Steps to Valve Selection The steps described in this section will help you identify the performance criteria needed to meet your application requirements and select the right valve. Step 1 – Calculating CV Begin by calculating the valve flow coefficient (CV) using: operating pressure differential; flow rate for your application; Specific Gravity; and in some circumstances, temperature. If you already know your CV please go directly to Step 2. CV combines the effects of all flow restrictions in the valve into a single number. CV represents the quantity of water, at 68°F and in gallons...

Sensors & Controls Step 2 - Valve Function Identify how your valve will function in your application. Pick from the choices below. An important note regarding Cv and valve function: The Cv calculated will apply to either the Body Orifice or the Stop Orifice depending on For example, the Stop Orifice for a 3-way normally closed valve, when de-energized, is the exhaust port. In other words, Cv is calculated using the specific Inlet Pressure (P1) and Outlet Pressure (P2) for the flow paths described below. Blocked Flow Free Flow DE-ENERGIZED ENERGIZED DE-ENERGIZED ENERGIZED 2-WAY NORMALLY CLOSED...

Step 3 - Identify Your Valve Series Select possible valve series candidate using the overview charts below. Begin by choosing the category for your application: • General Purpose «Isolation «Cryogénie Using the charts, select maximum operating pressure differential (MOPD), the CY, function, and additional specifications needed for your application to select possible valve series. The detailed performance specs for each series are located on the corresponding pages listed on the chart. •Consult factory for higher MOPD Step 4 - Make Your Selection and Configure Your Valve Complete your valve design...
