Straight-through large flow passage design minimizes hydraulic losses. In typical DN50 applications at flow velocities ≤2 m/s, head loss is controlled to <0.3m (1 ft), preserving pump suction-side NPSH margin and preventing cavitation in critical applications requiring reliable prime retention.
Flexible sealing solutions accommodate diverse operating conditions: elastomeric sealing for ambient freshwater applications and metal-to-metal sealing for elevated temperature services. Body materials span cast iron, brass, SS304/316L, PVC, and PP, paired with NBR, EPDM, or PTFE seals—supporting temperatures up to 120°C (248°F) for metal bodies, 90°C (194°F) for PP, and 60°C (140°F) for PVC configurations.
Bottom-mounted quick-release mechanism enables field cleaning and maintenance without pipeline disconnection. This design reduces maintenance downtime by approximately 40% compared to conventional installations, particularly beneficial for deep well and suction lift applications where accessibility is limited.
Available with dual-disc or damped slow-closing mechanisms to reduce light-to-moderate water hammer effects in high-frequency cycling applications.

Technical and commercial questions commonly asked by process engineers and procurement teams.
Our foot valves are manufactured in PN10-PN25 (150-600 PSI) pressure ratings with temperature range -10°C to 120°C (14°F to 248°F). Materials include cast iron, ductile iron, brass, stainless steel 304/316L, PVC, and PP. Polymeric materials are temperature-limited: PP ≤90°C, PVC ≤60°C. All metallic constructions comply with ASME B16.34 and DIN 3352 standards for dimensional accuracy and pressure containment.
Standard mesh configurations capture 1-3mm particles, with custom options down to 0.5mm available. Selection depends on upstream debris size and pump suction requirements. Coarser mesh (2-3mm) provides lower pressure loss for high-flow applications, while finer mesh (0.5-1mm) offers enhanced protection against valve disc jamming and pump impeller wear. Stainless steel 316L mesh is recommended for corrosive environments.
Our straight-through flow design minimizes pressure losses. For DN50 at flow velocities ≤2 m/s, head loss is typically <0.3m (1 ft), preserving critical NPSH margin for centrifugal pumps. Larger sizes maintain proportionally low loss coefficients. This performance advantage reduces operational energy consumption compared to traditional elbow-type foot valves while ensuring reliable suction-side priming retention.
Optional damped closure mechanisms control disc closing velocity through hydraulic restriction or dual-disc configurations. This reduces pressure surge magnitude during pump shutoff, particularly beneficial for moderate head systems. For high-head applications (>50m), we recommend combining foot valves with dedicated slow-closing check valves positioned upstream for comprehensive surge protection and extended system component life.
Elastomeric sealing uses NBR for general water service, EPDM for drinking water and mild chemicals, or FKM for elevated temperatures. Metal-to-metal sealing provides fire-safe performance and extended temperature capability to 120°C. Sealing materials are matched with body materials and process chemistry, including compatibility with seawater, weak acids/alkalis, and industrial cooling water applications.
