Description

Alta-Robbins unique valve design incorporates a fully contained soft seat that provides durability and longer lifetime. Tight shut-off is easily achieved with very low torque, yet the valve is rugged enough to withstand overtightening.

• Multiple valve configurations, including dip tube and rupture disks
• Temperature range: -40° to +120°C
• Available stainless-steel or sulfinert-treated

Dip Tube
Provides a headspace above liquefied gases so that, should expansion occur with an increase in temperature, the pressure is not dramatically increased. The dip tube is welded directly to the male inlet of the valve and cut to a length of up to 5.25 in.

Rupture Disks
Function to protect sample cylinders from overpressurization by venting to the atmosphere. The pressure rating on the rupture disk should always be lower than the cylinder.

Specifications

• Max. Temperature (Metric): -40°C to +120°C
