Sample valve with PFA-lined body and a gas-tight PTFE bellows seal — for taking samples from lined lines without opening the system, at transfer and loading lines, tank outlets and reactor sampling points. One page for both norms: choose the size (EN or ASME) and the lining, and send the configuration as a request for quotation.
Features
PFA-lined sample path
Body and sample path are lined with virgin PFA, like the line the valve sits in.
Gas-tight PTFE bellows seal
Hermetically sealed stem; gas-tight to DIN EN 12266-1, leakage rate A.
Suitable for vacuum service
PFA lining anchored in dovetail grooves in the body — suitable for vacuum service; limits per P-T diagram or on request.
Top-entry design
Maintenance is possible without removing the valve from the line.
Adjustable stroke limitation
Finely dosed sampling, also with closing-force amplification during sampling.
Bottle connection
GL connection for standard bottle DIN 168 with vent connection, or a customised connection to suit your system.
Vertical or horizontal installation
For installation in all environments with compatible sampling bottle adapters.
Security options
Stainless steel safety box against leakage from the bottle; padlock option prevents accidental operation.

FAQ
Questions we are often asked
PFA or PFA/AS lining?
PFA is the standard lining (virgin PFA). PFA/AS (antistatic) is for media where electrostatic charge must be led off. PFA/UP, PVDF, PP and UHMW-PE are available on request.
Which bottle connection is fitted?
A GL connection for a standard bottle to DIN 168, with vent connection. A customised bottle connection can be made to suit your existing system.
Can it be installed vertically or horizontally?
Yes, in both positions, with compatible sampling bottle adapters. The valve is top-entry, so maintenance is possible without removing it from the line.
Is the Provaron9 suitable for vacuum service?
PFA lining anchored in dovetail grooves in the body — suitable for vacuum service; limits per P-T diagram or on request.
Which documents come with each valve?
The valve is pressure-tested to DIN EN 12266-1 (leakage rate A, gas-tight) and EN 10204 3.1 material certificates are available. It is designed and manufactured to PED 2014/68/EU.
PFA or PTFE lining — what is the difference?
Both are fully fluorinated plastics with almost universal chemical resistance. PTFE cannot be melted, so PTFE liners are pressed and sintered. PFA can be melted, so we transfer-mould it into the valve body: the lining is dense, anchored in the body and follows complex shapes. If your specification says "PTFE-lined", a PFA-lined valve meets the same chemical duty — ask us for a comparison for your medium.
