High-Cycle Valve Stem Packing

Designed specifically for high-cycle applications, the packing sets are capable of withstanding operating pressures of up to 10,000 PSI while maintaining consistent low-leakage performance. Their optimized ring density and reinforcement structure effectively resist extrusion, stem scoring, and relaxation under repeated valve actuation. This makes them ideally suited for both rising stem and rotating-rising stem valves, including gate, globe, and control valves operating under severe pressure and temperature fluctuations.

Through advanced forming and precision machining processes, each packing ring delivers uniform stress distribution around the valve stem, reducing friction and torque while extending service life. The result is a sealing solution that minimizes fugitive emissions, reduces the need for gland adjustment, and significantly lowers maintenance frequency and total cost of ownership.

Proven in high-cycle and critical-service environments, these innovative packing solutions ensure long-term reliability, operational safety, and maximum valve performance, even under continuous operation and extreme working conditions.
