MT15~50-BT Explosion-Proof Solenoid Valve – Threaded
QUEEN SOLENOID VALVES
Discription
Explosion-Proof Rating: Ex d IIB T3 Gb
Certificate No.: (ITRI) 2026 No. 07-00115X
The MT15~50-BT is a threaded explosion-proof solenoid valve with connection sizes from 1/2" to 2". It is available in either Normally Closed (NC) or Normally Open (NO) configurations and is suitable for various media, including steam, air, inert gases, water, and oil.
The internal sealing components can be supplied with Teflon (PTFE) material according to application requirements, making the valve suitable for high-temperature media such as steam. The maximum operating temperature can reach 200°C. The MT15~50-BT is suitable for industrial equipment and piping systems where explosion-proof protection is required.

Order Information
Cautions
-
Before installation, please check whether the solenoid valve voltage is consistent with the power supply voltage.
- AC voltage tolerance: ±10%
- DC voltage tolerance: ±1% -
If there are unclean impurities in the fluid, a filter should be installed to avoid reducing the service life and hindering the operation of the solenoid valve.
-
Please install the solenoid valve in the direction of the fluid.
-
Pilot-operated solenoid valves require a minimum pressure to open.
-
Not suitable for freezing fluids.
