Description
The factory testing of every valve at full rating ensures a 150% tight shut-off, providing maximum reliability in critical applications. Designed according to JIS standards, the Pure-seal valve meets rigorous quality criteria for sealing and durability. The actuator mounting flange is built in compliance with ISO 5211, enhancing ease of use and compatibility with a wide range of actuators.
This valve features excellent sealing and elasticity, which contributes to its superior performance in demanding environments. Its one-piece through shaft offers maximum strength, further ensuring blow-out resistance, a critical factor in high-pressure applications. Additionally, the integrally cast disc position stop precisely locates the disc in the seat, maximizing both seat and seal life, providing added longevity and reduced maintenance requirements.
