The ZPL280W chlorine isolation valve and ZPL290W chlorine-regulated valve are dedicated linear motion control valves for chlorine(dry chlorine), liquid chlorine, and various high-risk media.
Product Overview
Their unique soft and metal sealing design ensures reliable sealing performance (with metal sealing achieving Class VI leakage rating). A bellows seal is added to the packing seal structure, forming a double-sealing mechanism that effectively prevents external leakage of hazardous media. The valve plug and valve seats sealing adopt highly corrosion-resistant PTFEand Stellitealloy, featuring stable sealing performance, safe and reliable operation, strong corrosion resistance, no internal or external media leakage, and easy operation. Primarily used to shut off (or open) pipeline media, they are suitable for liquid chlorine and chlorine gas applications in chemical pipelines. These chlorine-specific valves play a role in controlling and regulating chlorine flow, pressure, etc, during chlorine production, transportation, storage, and usage, ensuring the safe operation of the system.

| Features | Description |
| Superior Anti-Corrosion | The 16Mn valve body with Hastelloy C276 bellows and internals resists severe corrosion from chlorine gas and liquid chlorine, ensuring reliable operation in harsh conditions. |
| Anti-Vibration | The center flange reinforcement sleeve ensures stem concentricity and enhances rigidity. can effectively reduce valve vibration. |
| Bellows Protection Sleeve | The built-in bellows protection sleeve effectively shields against particulate damage while extending service life under vacuum conditions. |
| Interlocking Sealing Structure | The center flange utilizes a dovetail groove sealing structure, ensuring zero leakage at the valve body joint even under pipeline pressure fluctuations. |
| Superior Sealing | The plug and seat are hardfaced with Stellite alloy, ensuring resistance to medium erosion and significantly extending valve service life. |
| Bellows-Sealed Stem | The bellows and stem are integrated into a modular cartridge, enabling plug-and-play replacement to eliminate traditional bellows-to-bonnet weld leaks while simplifying maintenance. |
