Packing case conversion
We can convert your existing case to a purge design. Converting your packing case to a purge-gas system allows you to monitor your packing ring life and comply with tough emissions regulations. Our standard purge design employs a two groove T-cup. If the length of the assembly is limited, a single groove cup arrangement is used.

And the seal between the valve stem of the spiral motion valve and the fixed body.
The packing component is a floating flat sealing element structure consisting of several chambers. It mainly includes packing chamber, throttle ring, lock ring, seal ring, spring, etc. The lock ring and the outer ring of the seal ring are tightly clamped by the tension spring. After the operation, the gas pressure and the spring force are mainly applied to the piston rod. For sealing.
