Type 92B Pressure Pressure Regulator is the standard for the industry. It can withstand dirty operating environments while providing accurate and stable pressure control. Type 92B steam regulator is designed to provide decades of continuous service. Type 92B regulator is applied as a main pressure reducing valve in industrial process heating applications such as heat exchangers, evaporators, digesters, and reactors.

Type 92C is a cost effective pressure reducing regulator used in steam service. This valve is available with a Type 6392 pilot or without a pilot for use as a pressure-loaded regulator. The pilot-operated version uses inlet pressure as the operating medium; no separate air supply is required. The pressure-loaded version is used where remote adjustment of the valve pressure setting is required.

Type HSR direct-operated, spring-loaded pressure reducing regulators provide control in residential, commercial, and industrial applications for natural, manufactured, or liquefied petroleum gases.Internal relief across the diaphragm helps minimize overpressure. Any outlet pressure over the start-to-discharge point of the nonadjustable relief valve spring moves the diaphragm off the relief valve seat, allowing excess pressure to vent. Regulators meet ANSI B109.4/CGA 6.18.

Fisher 289 Series relief valves are spring-loaded throttling relief valves used as downstream pressure regulators to protect the system from overpressure. A smooth throttling action minimizes pressure surges in the system during relief operation. 289 Series relief valves are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. 289 Series relief valves are designed for pressure control; they are not ASME safety relief valves.

T208 Series may also be used as backpressure regulators or relief valves.

The T205 Series tank blanketing regulator is a direct-operated and spring-loaded regulator. The T205 Series maintains a slightly positive pressure to prevent a stored liquid from vaporizing into the atmosphere, reduces liquid combustibility, and prevents oxidation or contamination of the product by reducing its exposure to air.

Type Y692 gas blanketing regulator is a pressure reducing self-operated regulator with internal registration requiring no downstream control line. It is used for accurate pressure control on very low-pressure blanketing systems. The regulator will maintain a positive vessel pressure reducing the possibility of vessel wall collapse.

Y692VB Series vacuum breakers are used in applications where an increase in vacuum must be limited. An increase in vacuum beyond a registered value on the diaphragm of the Y692VB Series will open the regulator to allow atmosphere or a positive pressure to enter the system and restore the controlled vacuum to its original pressure setting.
