MAXSEAL ICO4-PST

The MAXSEAL ICO4-PST series is a highly reliable direct-acting solenoid valve with global certifications, frequently utilized in Safety Instrumented Systems. For over 20 years, it has set the industry standard for air control and pneumatic switching in Oil & Gas, Petrochemical, and Refinery applications, operating effectively in both upstream and downstream solutions. The ICO4-PST is available as a 2/2, 3/2, or 5/2-way poppet valve, with line media applied to inlet port A. When the solenoid is energized, the valve opens, allowing flow to outlet port B. Once power is removed, a spring mechanism closes the valve, and exhaust occurs through port C. This model incorporates the ISO4-PST feature, enabling operators to address all requirements for partial stroke testing without compromise, ensuring reliable performance in demanding environments.
