Diaphragm Valves

We extended our program with a NEW line of Diaphragm Valves from the company SMC. These valves are available in manual and pneumatic operated versions with different flange fittings. Diaphragm Valves are very popular in gas-cabinets.

Pressure Burst Disk

Also very popular is our Pressure Burst Disk. This product prevents the occurrence of overpressure during venting a vacuum chamber. The fully Stainless Steel housing will break as soon as the internal pressure exceeds  0,8 Bar.

Gas-independent Vacuum Sensor

The InstruTech Micro Bee Vacuum Sensor is a gas-independent capacitance vacuum sensor. The Micro Bee is available in Full-Scale versions: 1000, 500, 200, 100, 50, 20 and 1 Torr. The pressure range goes down to 0,05% from Full-Scale.
