Description
EE/ EK Series Characterized Control ValvesThe Chemline EE/ EK Series Characterized Control Valves provide extremely precise flow control of aggressive fluids. Valves flow characteristics (Cv vs. lift) follow theoretical linear or equal percentage curves through the entire range of stem travel. This is accomplished with precision made replaceable seats and plugs in a wide variety of Cv values. The PTFE bellows shaft seal provides almost frictionless stem movement and provides over 10 years of maintenance-free operation on aggressive chemical services. Electrically Actuated (EE Series) Specs: Power Supply: 115 VAC/50/60Hz Current Draw: 0.23 amps Adjustable Opening/Closing Times: Control Input: 0-10 V or 0-20mA Optional Voltages: 230 VAC/50/60Hz, 24 VDC or 24VAC Pneumatically Actuated (EK Series) Specs: Actuator Housing: Glass reinforced Polyester Control Air: Max 90 psi Mounting Position: Optional Working Pressure:150 psi |
✓ Precise and Sensitive
Predictable and repeatable control of corrosive fluids. These valves respond smoothly and quickly to small changes in signal. Deadband and hysteresis is negligible
✓ Changeable Plugs and Seats
Valve CV may be changed later if fluid conditions change
✓ Low Maintenance
✓ Abrasion Resistant
Have outperformed metal valves on aggressive and crystallizing services
✓ High Rangeability
Valve characteristics (flow rate vs. stem lift) follows the theoretical curves through the entire range of opening including extreme ends of travel
✓ Class IV Leakage
Rate is 0.01% of rated capacity according to ANSI B16.104-1976
✓ Large Choice of Cv Values
H18 standard Cv’s from 0.11 to 105.00, Smaller Cv’s down to 0.003 are also available
