Manifold flood valve assembly

A dispensing system comprising:

• an inlet manifold comprising an inlet port and a plurality of outlet ports wherein the inlet port of the inlet manifold is fluidically coupled to a source of a diluent;
• a flush manifold comprising a plurality of intake ports and an outlet port;
• a plurality of eductors, each eductor comprising an inlet port, a pickup port, a discharge port, and a venturi fluidically coupled to each of the inlet port, the pickup port, and the discharge port, wherein the inlet port of each eductor is fluidically coupled to an outlet port of the inlet manifold, the pickup port of each eductor is fluidically coupled to a source of a chemical product, and the discharge port of each eductor is fluidically coupled to an intake port of the flush manifold;
• a check valve fluidically coupled to the outlet port of the flush manifold and arranged to maintain the flush manifold substantially full of fluid between dispensing operations;
• and
• a vent valve fluidically coupled to an outlet of the check valve.

A dispensing system comprising:

• an eductor comprising:
• an inlet port fluidically coupled to a source of a diluent,
• a pickup port fluidically coupled to a source of a chemical product,
• a discharge port fluidically coupled to an intake port of the flush manifold and configured to discharge a chemical solution, and
• a venturi fluidically coupled to each of the inlet port, the pickup port, and the discharge port, the venturi being configured to draw the chemical product into the eductor in response to the diluent being coupled to the inlet port such that the chemical product is mixed with the diluent to form the chemical solution;
• a check valve fluidically coupled to the outlet port of the flush manifold and arranged to maintain the flush manifold substantially full of fluid between dispensing operations;
• and
• a vent valve fluidically coupled to an outlet of the check valve,
• wherein the check valve comprises:
• a first body portion forming a check valve inlet;
• and
• a second body portion coupled to the first body portion, the second body portion forming a check valve outlet;
• a plug assembly housed within the first body portion, the plug assembly comprising:
• a plug comprising:
• a plug body with two planar surfaces opposite one another with a groove formed between the planar surfaces;
• a stem extending from the plug body, and
• an O-ring captured within the groove;
• a valve plate secured between the second body portion and the first body portion, the valve plate comprising:
• a central opening surrounded by an annular wall, wherein the stem of the plug extends through the central opening, and
• a plurality of apertures arranged circumferentially around the valve plate and radially outward of the annular wall;
• and
• a spring positioned between the plug assembly and the valve plate, wherein the plug assembly is free to move linearly along a central axis of the check valve against a force of the spring.
