    AI Overview
    High elasticity valve inserts, often made from specialized elastomers like polyurethane or EPDM, are designed to offer superior sealing, wear resistance, and flexibility in demanding applications. They are commonly used in industrial, hydraulic, and oilfield equipment to provide a tight, reliable seal against high pressure or abrasives. 
    Key Applications and Types 
    • Frac Pump Valve Inserts: High elasticity polyurethane inserts (e.g., 4.5-inch sizes) are used in fracturing pumps for oil and gas, offering high wear resistance and oil resistance.
    • Resilient Seated Valves: EPDM or rubber inserts are used in butterfly and gate valves, relying on elastic compression to create a bubble-tight seal.
    • Hydraulic Cartridge Inserts: Poppet-type cartridge valve inserts offer high flow and efficiency, with specialized designs for flexibility and lower leakage.
    • Check Valves & Safety: Soft-seated inserts and one-way expulsion valves are used in backflow prevention and fluid control. 
    Material Characteristics 
    • Polyurethane: Known for extreme durability, wear resistance, and high elasticity in hydraulic applications.
    • EPDM: Provides superior resistance to weathering, oxidation, and heat, making it suitable for long-term sealing.
    • Nitrile Rubber (NBR): Used for excellent resistance to oil and hydraulic fluids.
    • Silicone: Used for extreme temperature stability. 
    Key Benefits 
    • Sealing Efficiency: High elasticity allows the insert to conform to surfaces, correcting small imperfections for a better seal.
    • Durability: Materials are engineered to be "virtually indestructible" in certain applications.
    • Operational Benefits: These inserts allow for easier valve rotation and longer service life under high-pressure conditions.
