Abstract: A manifold can determine a turnover scheme including a target turnover schedule of target turnover levels, based on an operation schedule and efficiency setting for a fluid distribution. Each target turnover level can correspond to a volume of fluid to be cycled through the fluid distribution system over a period of time. The manifold can operate respective valves and a supply device based on a target turnover level and determine a current turnover level from a flowrate detected by a flow sensor for at least one of the valves. The manifold can receive a current usage of the fluid distribution system and determine a required turnover level. An override status for the turnover scheme can be based on the efficiency setting and a comparison of the current, target, and the required turnover levels, and the manifold can operate respective valves and the supply device based on the override status.

Abstract: A fluid pressure reducing valve apparatus includes a pressure reducing valve. The valve has: a body containing a fluid-flow chamber, a liquid supply orifice into the chamber, a liquid outlet from the chamber, a regulation plate opposed to the orifice, a spring acting to urge the plate towards the orifice, and a diaphragm between the plate and the body to close the chamber between them.

Abstract: A ventilation control valve for a fuel tank is disposed in a ventilation passage which communicates an inside and an outside of a fuel tank. The ventilation control valve includes a float that floats on a liquid level of a fuel and moves up and down. The ventilation control valve includes a valve mechanism which switches a passage sectional area of the ventilation passage in conjunction with the float to an open state and a restricted state in which the passage sectional area is restricted from the opened state. The float has a volume chamber in which volume changes in accordance with a vertical movement of the float. A control gap as a flow rate adjusting mechanism is formed between the cylindrical wall of the float and the cylindrical wall of a case. Due to the control gap, the volume chamber functions as a damper.

Abstract: An indicator adapted to provide a visual indication of an over pressure situation in a system. The indicator (also referred to as a pop indicator), includes a main body, a piston that is disposed in the main body, and one or more O-rings disposed around the piston. Initially, the piston is in a first position where the piston is retracted into the body. However, when an over pressure situation occurs, the pressure causes the piston to move in a direction out of the main body against a friction force created by the O-ring. When the piston is moved, i.e., popped, then end of the piston extending out of the body provides a visual indication.

Abstract: For determining the operability of a fluid driven safety valve, a method comprising the following steps is described: A partial stroke test is performed on the safety valve, resulting in a stroke-pressure curve. The stroke pressure curve is extrapolated (330, 340) beyond the measured range (360) up to the safety closing position (350). From the extrapolated stroke-pressure curve, the closing pressure reserve (320) can be determined. In this way, the functionality of the safety valve can be checked during operation.
