Order Sample Valve | DIN-ANSI | Corrosion Resistant Sampling

Reliable Sampling Under Pressure

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.

Proven Performance

Industry Applications

The Provaron9 sample valve, with its virgin PFA lining and gas-tight PTFE bellows seal, is built to meet the highest safety and purity standards in process industries. Its resistance to highly corrosive, permeating, or reactive media makes it especially valuable where traditional materials like stainless steel or standard plastics fall short. From toxic sampling in chemical plants to aseptic draws in pharmaceutical lines, the Provaron9 delivers repeatable performance and total process containment — making it an essential tool wherever sampling accuracy, operator protection, and product integrity are non-negotiable.
