high pressure bidirectional solenoid valve

BDMZ Series High Temperature Stainless Steel Bidirectional Solenoid Valve

The BDMZ Series Bidirectional Solenoid Valve is engineered for high-pressure piping systems requiring reliable fluid reversing, shunting, or multi-directional flow control. Featuring a robust dual-coil structure and a premium stainless steel body, this heavy-duty valve is designed to handle demanding industrial media with exceptional sealing performance and zero backflow leakage. With a maximum working pressure of up to 10MPa (100 Bar), it is the ideal choice for high-pressure automation, hydraulic circuits, and specialized fluid management systems.

Key Features

True Bi-directional & Reversing Control: Specially structured to control and withstand medium flow in both directions, preventing backflow and ensuring stable line pressure.
High Pressure Capability: Built to endure extreme working conditions, supporting a wide pressure range from 6.4MPa up to 10MPa (model dependent).
Premium Material Construction: Precision-machined from high-grade Stainless Steel 304 / 316, offering superior corrosion resistance, chemical compatibility, and extended service life.
Dual-Coil Efficiency: Equipped with reliable dual electromagnetic actuators for precise, responsive switching between fluid ports.
Flexible Specifications: Available in multiple port sizes from G1/2″ to G2″ (DN15 to DN50) to seamlessly integrate into various industrial piping standards.
