Sampling Cylinder Valves and Accessories Sampling Cylinders


Safety Relief Devices – Saf-tee™ relief devices can be used with HOKE sampling cylinders as an inexpensive safety device or as a pipe size adapter for connecting valves in the make-up of cylinder assemblies. Two basic models are available to satisfy most pressure ranges. Spring relief models are recommended for applications where re-closure is required. Rupture Disc models are supplied with a pre-bulged rupture disc which provides excellent resistance to a broad range of hold-down plug and rupture disc to prevent damage due to torque transmission during assembly. A safety screen minimizes fragment release through the plug vents. The maximum operating system pressure should be limited to 80% of the nominal rating of the rupture disc for static operating pressure and ambient temperature. It should be limited to 70% if pressure pulsations occur or used at elevated temperature. The burst tolerance is within the ASME code guidelines

Cylinder Valves
1) 1700 Series Heavy Duty Cylinder Valves Heavy duty, 6000 psig compact line of 316 stainless steel and Monel® forged body globe pattern valves features an integral bonnet suitable for ¼ ˝ and 3⁄8˝ NPT ended cylinders.
2) 1900 Series Cylinder Valves This durable line of angle pattern valves features a low profile shrouded handle which protects the valve against damage. Dyna-Pak TFE wafer packing provides a leak tight seal with low operating torque even at 6000 psi (414 bar) pressure.
3) 2400 Series ½ ˝ Cylinder Valves 2400 Series 316 stainless steel, forged body angle pattern valves, come with a union bonnet for increased safety and ease of maintenance. Available with pressure rupture discs or spring relief devices as an integral part of the valve.
4) 3700 & 3800 Series Cylinder Valves The 3700 & 3800 Series, 5000 psig forged body cylinder valves are
supplied in stainless steel for cylinders with 1⁄8” through 3⁄8” NPT threads.
