PFA Lined Sample Valve: Features, Measurements & Materials

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.

Sample Valve Features

  • Seal Integrity


    A heavy-duty bellows seal on the stem and FEP-covered O-ring seals on the adapter maintain a reliable, leak-proof seal throughout operation.

  • Gas-tight

    
to DIN 12266-1 leakage rate A

  • Top-entry design


    Maintenance possible without removal

  • Sample Glasses

    
GL connection for standard bottle DIN 168 with vent connection or customized bottle connection to adapt to your existing system

  • Vertical installation & Horizontal Installation 


    for uncomplicated installation in all environments with compatible sampling bottle adapters

  • Adjustable stroke limitation

    
finely dosed sampling, also with closing force amplification during sampling

  • Sampling Process Efficiency


    An annular cavity flow path enables smooth fluid flow, while the adapter’s vent hole safely exhausts air from the sample bottle.

  • Security Features (Optional)


    The valve’s stainless steel safety box protects against leakage from the sampling bottle, while a padlock option prevents accidental operation
