53-SY Series Solenoid Valve

SMC Solenoid Valves (also known as directional control valves) coordinate the action of various downstream devices including air cylinders, air piloted pumps, slide tables, grippers and rotary actuators.  The 53-SY series solenoid valve is the intrinsically safe version of out flagship of pneumatic valve product line. The SY series offers flexbility, reliability and sonic conductance (throughput) within a small footprint.

The intrinsically safe solenoid valve complies to US913 and CSA157.


Intrinsically Safe vs. Explosion Proof


  • Explosion Proof aim to contain explosions inside enclosures
  • Intrinsic Safety (IS) keeps from ever happening at all. It limits electrical and thermal energy
  • Intrisically Safe makes most sense in process automation where equipment are low energy level (24VDC, 300mA or less)
