APCO Check Valves
APCO Check Valves
APCO offers one of the most comprehensive ranges of check valves in the market, each engineered to deliver reliable backflow prevention, minimize pressure surges, and support application specific flow control needs. This guide consolidates key performance attributes of each design to assist engineers and specifiers in selecting the most suitable valve for their application.
Whether you’re designing for clean water, wastewater, chemical service, or high-performance pump discharge, this resource provides side-by-side comparisons and technical insights to ensure proper valve selection based on flow characteristics, shut-off performance, and surge mitigation needs.
What are Check Valves?
The primary function of a check valve is to permit flow in one direction while preventing reverse flow in the opposite direction. To achieve this, check valves are typically installed on the discharge side of a pump, where they play a critical role in system protection. When the pump stops, the check valve automatically closes to prevent backflow and potential system drainage, thereby maintaining the integrity of the fluid system and protecting upstream equipment.
Which Check Valve Should I Use?
A wide range of check valve designs are available, each offering distinct shut-off characteristics to suit various system requirements. Some check valves are designed exclusively for clean service, while others can handle both clean and dirty media. Additionally, certain check valves are engineered specifically for pump control applications, and custom-fabricated options are available to meet unique operational or system parameters.
