Solenoid Valves for Pneumatic and Hydraulic Control Systems
Solenoid Valves for Pneumatic and Hydraulic Systems (IMI Norgren, Maxseal, Herion)
At Nordenflow, we supply solenoid valves for pneumatic and hydraulic systems used in control, automation, and safety applications.
Solenoid valves control the flow of air or fluid by converting electrical signals into mechanical action, directly affecting system response time and operational reliability.
We focus on fast response, application support, and access to proven technologies like the Maxseal ICO2S, ICO3S and ICO4S series. We help customers ensure safe and consistent operation in demanding environments.
Our solenoid valves are engineered for high reliability in pneumatic and fluid control systems, including actuator applications and safety loops.
Available in stainless steel and other corrosion-resistant materials, they are suitable for harsh environments and continuous operation.
When You Need Solenoid Valves
Solenoid valves are required when fast, reliable control of air or fluid flow is critical for system performance, automation, or safety functions.
Electrical Signal Must Control Flow
When system operation requires converting electrical signals into immediate valve actuation for control or automation.
Fast Response or Shutdown is Required
Critical in emergency shutdown (ESD) systems and safety applications where rapid valve actuation is essential.
Unstable or Inconsistent System Behavior
When valve response is delayed, inconsistent, or unreliable due to improper signal or control components.
Pneumatic or Hydraulic Actuation Control
Used to control air or hydraulic supply for actuators, enabling automated valve operation.
Safety and SIL Requirements
Required in safety systems where reliability and compliance with SIL standards are essential.
Replacement or Upgrade
When existing solenoid valves fail, leak, or no longer meet system performance or safety requirements.

Engineering Scope
Solenoid valve performance is defined by response time, pressure conditions, and reliable signal actuation within control and safety systems.
Response Time
Switching speed is critical in control and safety systems, particularly for emergency shutdown (ESD) applications.
Operating Pressure Range
Selection depends on available air or hydraulic pressure to ensure reliable actuation without delay or failure.
Flow Capacity (Cv)
Valve sizing must ensure sufficient flow capacity for actuator operation and system response requirements.
Electrical Parameters
Voltage, power consumption, and coil characteristics must match system requirements for stable operation.
Environmental Conditions
Temperature, hazardous area classification (ATEX), and protection ratings influence material and design selection.
Functional Safety (SIL)
Solenoid valves used in safety systems must meet required SIL levels for reliability and fail-safe operation.
Incorrect selection of solenoid valves can lead to delayed response, unstable operation, or failure of safety systems.
