2J Series Angle Seat Valve
Product Features
- Pneumatic Control: Fast response without electricity. Highly suitable for flammable and explosive environments. Uses low control pressure to manage high-pressure fluid systems safely.
- Durable Materials: The valve body, connecting rod, and wetted parts are manufactured from high-quality stainless steel, offering strong corrosion resistance. Perfect for highly corrosive fluids and areas with strong magnetic fields.
- High Flow Design: Features a 45-degree angle seat structure paired with a streamlined inner cavity design. This drastically reduces flow path resistance, enabling smoother fluid flow and larger flow rates.
- Visual Indicator: Equipped with a valve position display device on the top of the actuator to visually observe the opening size. The indicator cap can also be replaced with a limit switch or an emergency manual override device.
- NAMUR Compatibility: The actuator interface utilizes a plug-in metal joint. A transitional connection plate allows for the direct, seamless installation of NAMUR standard solenoid valves.
- Flexible Installation: The actuator head can be freely rotated 360 degrees for easy mounting and air pipe connection in any orientation.
