What is the primary function of an underload valve?

The primary function of an underload valve is to reduce pressure, ensuring that the hose does not exceed its rated limits and potentially break. This is particularly important in aquatic pest control operations where hoses are routinely subjected to varying pressures. By managing pressure effectively, the underload valve helps maintain the integrity of the equipment, prolonging the lifespan of hoses and minimizing the risk of leaks or bursts during operation.

While other functions such as enhancing pump efficiency or preventing back-siphoning are useful in different contexts, the specific role of the underload valve is to manage pressure levels directly, protecting the equipment involved in the application process.
