Y-Type Air-Powered Drain Valve Product Brief:
Y-type pneumatic diaphragm trap valve is a steam trap designed specifically for draining condensate from thermal power plant equipment.Thermal Expansion Relief ValveThe product features a streamlined design close to a straight line, reducing flow resistance, employing the secondary throttling principle, minimizing erosion, and extending lifespan. The valve core and seat are made of solid hard alloy. The internal leakage upon closure is less than or equal to VI grade.Pneumatic Drain ValveIt features a removable and sealed mid-cavity design to prevent external leakage and is easy for maintenance. It serves as a signal for automated instruments, controlling the cutoff or opening of valves, thereby meeting the usage requirements of controlled parameters. Hence, it is widely used in remote control applications in power plants and other industries.

Product Features of Y-Type Air-Powered Drain Valve:

The valve disc sealing surface of the pneumatic drain valve is surfacing-welded with a hard alloy, which features mechanical properties, wear resistance, and erosion resistance, ensuring a long service life for the valve.
2. The valve stem packing uses imported special packing, which provides anti-leakage effectiveness, is durable, and easy to install and dismantle. The sealing at the packing box and valve body is achieved with a 316 high-grade flexible graphite gasket, assembled with a predetermined torque for reliability and to prevent external leakage.
3. Utilize pneumatic actuators as the actuating mechanism for effective valve control.
4. The filling box is designed with a high-pressure structure, ensuring sufficient strength and excellent thermal properties.
