A substrate block for a fluid delivery system is provided, the substrate block having an upper surface. The upper surface has an inlet substrate port and an outlet substrate port formed into the upper surface. A substrate fluid passageway extends from the inlet substrate port and the outlet substrate port. The substrate fluid passageway extends in a smooth arc which is free of corners or angular walls.

The present disclosure relates to an improved pilot valve assembly for a hydrant pit valve. The pilot valve assembly includes a poppet that is movable between an open position and a closed position. The poppet has a molded seal with an interlock feature to hold the seal rigidly. The pilot valve assembly also includes a manually reset mechanism. The reset mechanism can be horizontally positioned and can function to reset the pilot actuator for the next refueling operation. A lanyard can be connected to the poppet to be used a deactuation mechanism.

A waterproof cover includes an operation unit for pressing a manual button of a solenoid valve main body. The operation unit includes a flexible cap, a pin guide interposed between the cap and the solenoid valve main body, and an operation pin that is inserted in guide hole of the pin guide so as to be displaced freely. The cap includes a flexible pressing portion for a pressing operation. One end of the operation pin is in contact with or close to the pressing portion, and the other end of the operation pin is in contact with the manual button.

A faucet valve cartridge pulling tool comprising a housing, a stem screw, and a collar. The housing has a first end and a second end. The first end has a surface adapted to abut a portion of a faucet valve body. The stem screw has a first end and a second end. The stem screw includes a first threaded section and a second threaded section. The first threaded section is adapted to engage internal threading of a faucet valve cartridge stem located within the faucet valve body. The collar has internal threading engaging the second threaded section of the stem screw. Wherein, rotating the collar relative to the stem screw pulls the first threaded portion axially towards the second end of the housing.

A mounting structure for a fuel shutoff valve unit (U) includes a valve device (50) which is provided in a fuel tank (31) of a saddle type vehicle (1) and in which a breather passage (Y) which discharges volatile fuel to the outside is formed and a valve (51) which prevents leakage of liquid fuel is provided, wherein, in the saddle type vehicle including a filler tube (F) which is provided inside the fuel tank (31) and supplies fuel supplied from the outside to the inside of the fuel tank (31), a support member (B) which is provided on an outer peripheral surface of the filler tube (F) and supports the fuel shutoff valve unit (U) inside the fuel tank (31) is provided.

A spread faucet assembly, an installation kit, and an installation method are described herein. The spread faucet assembly has a spout assembly with a spout, a tailpiece, and at least one fluid inlet conduit. It also include at least one valve assembly having a shank, an fluid inlet conduit, a fluid outlet conduit and a valve cartridge, wherein the shank has an inner surface having a fluid receiving area in fluid communication with the valve cartridge and the fluid outlet conduit, the inner surface defines an opening in fluid communication with the valve cartridge and valve assembly fluid inlet conduit, and the valve cartridge is positioned in the opening. A connector is also included for coupling the at least one valve assembly fluid outlet conduit with the at least one spout assembly fluid inlet conduit. A self-turning nut assembly is also provided having a nut with an outer surface and a tightening sleeve having an outer surface with at least one outwardly extending projection for securing the nut to a fluid supply connection.

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.
