In industrial processes where precise fluid control is critical, even minor deviations can lead to production line stoppages or significant losses. The OMEGA SV-100 and SV-200 series solenoid valves provide reliable solutions for demanding industrial and laboratory applications, handling diverse media including liquids, steam, gases, and hot water.
The OMEGA SV-100/200 series features a modular design comprising three core components:
- Valve Body: Constructed from stainless steel or brass for superior media compatibility and extended service life.
- Wetted Components: Including isolation rings, valve materials, and O-rings made from corrosion-resistant, high-temperature materials for stable operation in harsh environments.
- Solenoid Coil: Designed for continuous duty operation with encapsulated protection against moisture, mold, and extreme conditions.
The valves meet NEMA 4 (IP65) protection standards and feature 1/2-inch conduit connections for secure electrical integration.
OMEGA offers three distinct actuation methods to accommodate varying pressure and flow requirements:
- Direct Lift Design: Combines the responsiveness of direct-acting valves at low pressures with the high-flow capacity of pilot-operated valves at elevated pressures.
- Direct-Acting: Features simple construction with rapid response times, though with limited pressure and flow capabilities.
- Pilot-Operated: Utilizes system pressure to drive valve operation through a pilot valve, enabling high flow rates at substantial pressures.
Proper valve selection requires careful consideration of five critical parameters:
- Flow Coefficient (Cv): Determines the valve's flow capacity.
- Media Compatibility: Ensures materials resist corrosion or contamination.
- Pressure Rating: Must exceed system maximum pressure.
- Temperature Range: Should accommodate system temperature variations.
- Connection Type: Must match existing piping configurations.
For incompressible fluids, selection focuses on:
- Flow coefficient (Cv)
- Flow rate (Q in GPM)
- Pressure differential (ΔP)
- Specific gravity (G)
Compressible media require additional considerations:
- Flow rate in standard cubic feet/hour (SCFH)
- Absolute pressure values (psia)
- Gas temperature (°F)
- Specific gravity relative to air
A 2 GPM flow of liquid (G=1.1) requires a valve with 10 psi differential pressure. Calculation yields a required Cv of 0.67, satisfied by the SV105 model (Cv=0.75).
For gas flow (500 SCFH, G=0.7) with 5 psid differential, the same SV105 valve meets requirements with its 0.75 Cv rating.
A single-acting spring-return cylinder requiring 44 psid differential pressure at 90°F would be appropriately controlled by the SV241 model (Cv=0.18, 150 psid rating).
