GFT 9 PFA Transfer Molding Meets Precision Engineering

PFA Lined Sample Valve

Provaron9
The Provaron9 PFA-lined sample valve offers a safe and reliable solution for extracting representative samples of corrosive, toxic, or high-purity media. Its hermetically sealed PTFE bellows ensure gas-tight operation (DIN 12266-1, leakage rate A), while the virgin PFA lining provides exceptional chemical and permeation resistance, even in vacuum conditions. Designed for user safety and process consistency, the valve includes automatic reset closure, low operating torque, and an optional padlock to prevent unauthorized access. Its conical seat geometry enables precise, leak-proof shut-off, and the adjustable stroke limiter allows fine dosing, including force amplification during sampling. With a top-entry design for easy maintenance, GL bottle connection with venting, and adaptability for vertical or horizontal installation, the Provaron9 is engineered for performance and durability in demanding process environments.
