During valve repair and refurbishment, careful inspection of gate, seats, and seal grooves is essential before installing new API 6A seal kits.

Surface reconditioning and dimensional checks help ensure that new seals operate within the intended design envelope. https://globalsealstech.com/product-category/oil-gas-seals/api-6a-gate-valve-seals/
