The **ZMQS Y Type Pneumatic Steam Trap** is designed with a new series of **Pneumatic Diaphragm Actuators** combined with a **Y-Type Steam Trap**. This trap functions as a control valve with a unique structure, making it ideal for precise steam management in industrial systems. Both ends of the trap are **welded**, ensuring compatibility with specific piping configurations.
The **pneumatic actuator** offers both **positive and negative action** options. In positive action, an increase in signal pressure causes the push rod to extend from the diaphragm chamber, resulting in an **air-closing style** when combined with the steam trap. In negative action, the push rod retracts into the chamber, creating an **air-opening style** with the valve. This flexibility allows for tailored control based on system requirements.
### Working Principle:
When a signal pressure is applied to the diaphragm chamber, it pushes the diaphragm, compressing the spring within the actuator. The valve stem then moves accordingly, adjusting the flow area between the valve disc and seat until the spring's counterforce balances the signal pressure. This mechanism enables **automatic adjustment** of key technical parameters.
The **ZMQSY/ZDLSY Series** of **Pneumatic/Electric "Y" Type Trap Valves** are specifically developed for use in **thermal power plant equipment**. These valves are engineered to provide efficient drainage and are suitable for a wide range of applications, including remote control in industrial environments.
Key features include:
- **Nearly linear flow design** to reduce flow resistance.
- **Dual throttling principle** to minimize erosion and extend service life.
- **Hard alloy plug and seat** for tight shut-off (leakage ≤ VI).
- **Compact sealing structure** for improved leak prevention and easier maintenance.
- **Suitable for flammable and explosive environments**.
- **Remote control capability** via control systems or instruments.
