offer an economical and dependable relief port to guard against
Autoclave Engineers offers universal safety heads in three series compatible in orifice size and maximum pressure rating with Autoclave Low Pressure, Medium Pressure and High Pressure valves, fittings and tubing.
Autoclave Low Pressure Series SS: Autoclave SpeedBite Ermeto-type tube connection, maximum rupture pressures to 15000 psi (1034 bar).
Autoclave Medium Pressure Series CSX: Autoclave Medium-Pressure coned-and-threaded tube connection, maximum rupture pressures to 20000 psi (1379 bar).
Autoclave High Pressure Series CS: Autoclave High Pressure coned-and-threaded tube connection, maximum rupture pressure to 110000 psi (7584 bar).
The 3/16F style features a 3/16” blow-out diameter and a flat seat which can be ordered in pressure range from 200 to 27000 psi (13.8 to 1862 bar).
The 1/4A style features a 1/4” blow-out diameter and an angular seat which can be ordered in pressures from 900 to 60000 psi (62 to 4137 bar).
The 1/4F style features a 1/4” blow-out diameter and a flat seat which is used for pressure above 60000 psi (4137 bar).
The 1/2F style features a 1/2” blow-out diameter and a flat seat which can be ordered in pressures from 500 to 10000 psi (35 to 690 bar).
ASME Safety Head - Autoclave now has an ASME Section VIII Div. 3 safety head assembly rated to 115000 psi (7929 bar). Contact the factory or your local sales representative for details and ordering information.
Materials and Features
Gauges - Pressure gauges are offered for use in low, medium and high pressure systems. Instrument quality gauges are available to pressure of 80,000 psi (5115.7 bar).
Autoclave Engineers Pressure Snubbers provide protection
to gauges and instrumentation from pressure surges, pulsation
and shock. The unique snubber design provides superior
instrument protection while not compromising instrument
accuracy or reaction time. This is accomplished by the use of
existing technology from our excess flow check valve with
additional design features.
When sudden flow is seen, the poppet will rise, blocking the pressure surge and a small bleed hole in the poppet will allow pressure to slowly equalize. When the pressure is equalized, the poppet will then drop back down allowing normal flow to the gauge. A filter is used to prevent the hole in the plug from becoming plugged. The snubber must be mounted in the vertical position as indicated on the unit.
Snubbers are offered in 316SS as standard, with either male, female or male/female connections in 1/4" and 3/8" sizes. Optional materials available upon request.
