Lower sealing

PRIMARY AND MAIN PROTECTION GUARANTEEING THE SAFETY OF THE SAMPLING POINT

BIAR offers three designs of stem gaskets with materials that can be adapted to the required temperatures, sampling pressures and rackings. These O'rings have been specially designed to withstand temperatures from -40 to +400°C (-40 to 752°F) as well as pressures from 0 to 100 bar (0 to 1450 psi).

Standard stem gasket

The Standard stem gasket is initially available in PTFE and can also be provided in Carbon PTFE or PEEK, depending on the sampling parameters. Both the PTFE and PEEK variants comply with FDA regulations.

Applications

Suitable for most applications
Liquids with few or no particles
In PTFE and PEEK, suitable for the food industry
Temperatures from -40°C (-40°F) to 280°C (536°F)
Pressures up to 16 bar (232 psi)

Advantages

Perfect sealing at low pressures and temperatures
Highly satisfactory chemical resistance, particularly in PTFE
Excellent durability
Simple, low maintenance

HP Stem Gasket

Thanks to this innovative design, the HP stem gasket fits even more tightly to the spindle. Available in three different materials, it is perfectly suited to the most complex sampling points, even those subject to extremely high pressures and temperatures. In its Pure PTFE and PEEK versions, it meets strict FDA standards, ensuring maximum reliability in any environment.

Applications

Prélèvements sous hautes pressions 40 bars (580 psi)
Liquides avec particules et / ou collants
Températures de -40°C (-40°F) à 280°C (536°F)

Avantages

Parfaite étanchéité à hautes pressions
Excellentes résistances chimiques particulièrement en PTFE
Utilisation avec des liquides se solidifiant
Conforme aux exigences de la FDA et adapté à l'alimentaire en PTFE Pure et PEEK

Stellite Stem Gasket

Metal-to-metal sealing suitable for sampling points with extreme pressures and temperatures. It is often the only solution when chemical, high-pressure, high-temperature and abrasion resistance are required. It withstands the same pressure (Pmax: 100 bar / 1450 psi) and the same temperature (Tmax: 400°C / 752°F) than the valve itself.
