  • Low weight wafer design provides up to 90% weight reduction compared to traditional full body swing check valve.
  • To meet special applications and service conditions; Prince offers flow rate analysis, silicone-free and oxygen cleaning, custom milling, hydrostatic and pneumatic testing, custom component design, and exotic materials.
  • Prince Figure 913 external spring wafer check valve removes the spring from the process flow to prohibit the possibility of fiber wrapping around the spring or chemical attach of the spring; which provides extended life in fibrous, caustic, and suspended solids applications.
