Fisher-ACE97 Series Pad-Depad

The 97 Series simplifies the process of make-up and vent by combining both functions in one unit. This series is a unique, patented valve which incorporates all the standard features in our Type ACE95 Series valves. 

We Have a Better Way: Gas In - Gas Out "One Unit"
The unit consists of a single actuator that controls the entire operation. Pad (make-up) and depad (venting) are controlled by the actuator.

The diaphragm in the actuator has a long stroke. It is biased by a single range spring set that controls both pad and depad setpoints independently.These setpoints are both adjustable.

At the bottom (lower pressure) of its stroke, the diaphragm acutates the pad valve to control the flow of inert gas to the tank vapor space.

Pump out of tank contents or a drop in vapor space temperature will cause the tank pressure to drop below pad setpoint. The diaphragm will move down and actuate the pad valve. Inert gas will be throttled into the tank.

As the pressure rises to pad setpoint, the diaphragm also rises. This deactuates the pad valve and flow of inert gas ceases. Pump in or a rise in vapor space temperature will cause the tank pressure to rise. The diaphragm will move upward and when the pressure reaches the depad setpoint, it will actuate the depad pilot valve. This throttles the depad main valve, venting the tank vapor space and controlling the pressure.

Both the pad valve and depad valve are plilot controlled (except for the 1/2" body pad valve). Shut-off is tight and positive. The inert gas supply is used to operate both valves and provides a positive force against the valve seats to ensure tight shut-off. The valves are soft seated and bubble tight up to their setpoints.

Typically, the pad valve operates within a 0.5 inch water column band below its setpoint.

66 Series Pressure Reducing Regulators




The Type 66 self-operated regulator maintains a reduced outlet pressure while satisfying the downstream flow demands.  The Type 66Z and 66ZZ self-operated regulators also control a reduced outlet pressure; however, both have springs sensitive to negative pressures and can be used for vacuum regulation.  Each regulator type has a balancing diaphragm which increases accurate and sensitive response to pressure changes by reducing the unbalanced forces acting on the valve plug.

Type ACE95 Series Tank Blanketing Valve

Tank blanketing is the process of using a gas, such as nitrogen, to maintain a slightly positive pressure in an enclosed storage tank. Tank blanketing prevents a stored product from vaporizing into the atmosphere, reduces product combustibility, and prevents oxidation or contamination of the product by reducing its exposure to air. Tank blanketing is utilized with various products, including: adhesives, pharmaceuticals, pesticides, fertilizers, fuels, inks, photographic chemicals, and food additives.

Y690A Series Tank Blanketing Valve

The Y690A Series Gas Blanketing Regulator System reduces a high-pressure gas, such as nitrogen, to maintain a protective environment above any liquid stored in a tank or vessel. The regulator system replaces the volume of vapors with a volume of blanketing gas to prevent the internal vessel pressure from decreasing, when liquid is being pumped out or when the vessel is suddenly cooled, causing vapors to contract. In both cases a slight positive vessel pressure prevents outside, air, moisture and other contaminants from entering the vessel. The Type Y690A is a direct-operated regulator used for accurate pressure control on very low pressure blanketing systems. Downstream pressure is sensed through a pitot tube installed in the lower casing of the regulator, thus no external control line is required. The Type Y690AM uses a control line to more accurately control the pressure if the regulator is mounted away from the tank.
