Production Requirements

1. For systems handling pure liquids, pure gases, and gas-liquid mixtures (e.g., pharmaceutical/food pipelines):

Traditional metal-seated valves are prone to contaminating the process medium and experiencing seal failure. Soft-seated ball valves have become the essential choice due to the properties of their non-metallic sealing materials:

o Zero medium contamination

o Ultra-low leakage rate

2. For automated processes with frequent operation (e.g., chemical plant DCS control):

Soft-seated ball valves outperform metal-seated valves in both service life and operability:

o Ultra-low friction coefficient: The operating torque is only 20% of that of metal-seated valves, reducing actuator power consumption.

o 500,000-cycle maintenance-free service life: The wear resistance and self-lubricating properties of PTFE support the thousands of daily operations required in chemical valves.

o Low-temperature adaptability: A specialized PCTFE formulation withstands temperatures as low as -196℃ (for LNG liquid nitrogen service), while metal-seated valves are prone to brittle fracture and leakage at cryogenic temperatures.

Cost Requirements

1. Cost reduction benefits for enterprises: Soft-seated ball valves use less raw material for their core components, offering a competitive procurement cost advantage that aligns with corporate cost-saving goals.

2. Efficiency gains for enterprises: A lower failure rate translates to higher operational efficiency.
