Abstract
The invention in the simplest form is a dispenser valve with an increased flow capacity. The device is particularly suited for dispensing liquids, and has a plurality of individual thin and streamlined elevated standoffs that serve as the spring seat, lowering flow losses and providing a larger flow path area or particulate matter included in the liquid. In addition, the ball check valve chamber is funnel shaped, creating an efficient flow for the dispensing liquid regardless of the viscosity or particulate of the liquid. The unit increases discharge capacity, reduces clogging, improves efficiency, and allows the unit to dispense highly viscous and gritty materials.
