Product Features

1.Air piloted and can be used non electric flammable and explosive environment. The start-up pressure is low; and the high pressure could be controlled by the low pressure.

2.The accessories and slide bar are made of stainless steel which are of excellent rustproof quality. The seals are made of Teflon and can be applied extensively in areas with high temperature and strong corrosive liquids.

3.The structure of valve angles at 45 degrees with streamline inner chamber design. The reduced tunnel resistance allows liquid to run more smoothly thus achieving high flow. Filtration core is added at inlet port to prevent the entrance of impurities and extend life span of the seals.

4.Actuator is fitted with visual position indicator. This allows for visual checking and adjustment of flowrate.

5.Control point is made of metal insert. Mounting plate can be used for NAMUR value.

6.The actuator part can be rotated at 360 degrees and is easily installed.

Airtac 2J Series Steam Angle Seat Valves: High-Frequency Control
The Airtac 2J Series is a premium line of 2/2-way pneumatic angle seat valves engineered for the precise control of water, neutral liquids, gases, and saturated steam.

Recognized as a benchmark in industrial fluid control, the 2J Series offers a high-flow, cost-effective alternative to traditional ball and solenoid valves, ensuring exceptional durability up to 180°C.

🔹 Core Technical Advantages
• High Temperature Durability: Constructed with high-grade 304 or 316L stainless steel (CF8/CF8M) and equipped with PTFE seals for long-term reliable service.
• High-Flow Efficiency: The unique Y-pattern design provides a significantly higher flow rate (Cv value) compared to standard globe valves while minimizing flow resistance.
• Anti-Water Hammer Design: Specifically engineered to protect piping systems from pressure surges.
• Versatile Actuators: Actuator sizes from 40mm to 125mm with NC, NO, and Double Acting (DA) configurations.
• 360° Flexible Installation: The actuator rotates 360° for easy mounting in tight spaces.
