ZMQSY Pneumatic Steam Trap is a high-performance control valve designed for efficient steam and air discharge in industrial applications. It combines a new series of Pneumatic Diaphragm Actuators with a Y-Type Steam Trap, offering precise regulation and reliable operation. The Y-Type Steam Trap functions as a control valve with a unique design, making it ideal for use in tanks, pipes, and vessels.
This pneumatic steam trap features welded ends, ensuring compatibility with specific piping systems and enhancing structural integrity. The actuator offers both positive and negative action modes. In positive action, an increase in signal pressure pushes the diaphragm, resulting in an air-closing style. In negative action, the push rod retracts into the diaphragm chamber, creating an air-opening configuration. This flexibility allows the trap to adapt to different operational requirements.
The working principle of the ZMQS Y-Type Pneumatic Steam Trap involves signal pressure acting on the diaphragm, compressing the spring within the actuator. This movement adjusts the flow area between the valve disc and seat until the spring force balances the signal pressure, enabling automatic adjustment of technical parameters.
Designed for thermal power plant equipment, the ZMQSY/ZDLSY series of pneumatic/electric "Y" type trap valves are engineered for optimal performance. They feature a nearly linear flow design to reduce resistance, a dual throttling mechanism to minimize erosion, and hard alloy sealing surfaces that meet leakage class VI standards. The compact structure allows for mid-cavity sealing, improving leak prevention and ease of maintenance. These valves are suitable for use in flammable and explosive environments.
They can be controlled by signals from control systems or instruments, allowing for accurate regulation of process parameters. Widely used in power plant remote control systems, they ensure safe and efficient operation under various conditions.
