世伟洛克^® 隔膜密封阀

世伟洛克隔膜密封阀通过尽可能地减少截流区，并利用完全可清扫流道便于进行吹扫操作，在实现有效切断流体的同时提高了系统效率。此类阀门具有较长的循环寿命，并有多种尺寸、材料和配置可供选择，以满足高纯和超高纯 (UHP) 应用的系统要求。

Swagelok diaphragm-sealed valves come in various sizes, materials, and configurations to meet the needs of high-purity and UHP applications. They feature flow coefficients ranging from 0.20 to 13. Their fully swept flow paths and corrosion-resistant construction make them ideal for applications where cleanliness is crucial. Users can choose from manual, pneumatic, and locking actuator options.

Swagelok diaphragm-sealed valves can be used in atomic layer deposition (ALD), high-flow, modular gas system, thermal-immersion, and ultrahigh-purity applications requiring fluoropolymer component construction.

Swagelok springless diaphragm valves for modular gas systems are easy to install, provide a visual indication of flow direction, and have a seat design that improves thermal stability
Swagelok bulk gas diaphragm valves offer a combination of strength, flexibility, and cycle life to support a wide range of ultrahigh-purity shutoff, bulk-gas distribution, and isolation applications
Swagelok thermal-immersion diaphragm valves can be entirely contained within a high-temperature, high-purity environment, making them strong options for ALD and precursor delivery applications
Swagelok ultrahigh-purity fluoropolymer diaphragm valves offer a strong solution for UHP chemical distribution, DI water, and bulk chemical delivery systems
