Soft Seat Needle Valve - BuTech

Traditional metal-to-metal needle valves often struggle to maintain a reliable seal, especially in demanding gas applications.

The BuTech Soft Seat Needle Valve is engineered to overcome these limitations by combining proven needle valve technology with chevron packing and a soft seat ensuring a secure, leak-tight closure and reliable performance across a wide range of industrial gases.

Engineered for precision and reliability, the BuTech Soft Seat Needle Valve is the ideal solution for medium-pressure gas applications where leak-tight sealing is critical.

Unlike traditional metal-to-metal seated valves, this advanced design features chevron packing and a soft seat, ensuring a secure seal even under demanding conditions.

Engineered for high-performance containment, this valve helps maintain system integrity by preventing media escape upstream and minimizing pressure loss downstream.

Rigorously tested to ISO-19880-3 standards with nitrogen and helium for up to 102,000 pressure cycles, this valve delivers durability and reliability in even the most demanding environments.

Perfect for use in hydrogen refueling stations, compression systems, and general gas shut-off applications, this valve delivers consistent performance across a wide range of gases including hydrogen, nitrogen, helium, and argon.
