Product Description
- The LVA 2/2-way valve from SMC is suitable for use as a shut-off valve for ultra-pure media and chemicals.
- Typical applications include IC manufacturing, the chemical and pharmaceutical industries, and food processing.
- Further applications can be found in medical technology, analytical instruments and cleaning equipment.
- The valve can also be used for pure blow-off air.
- The SMC LVA 2/2-way valve consists of a PPS housing, a PPS actuator head and a PTFE diaphragm.
- The pneumatically operated valve for ultra-pure media used in the chemical industry is fitted with a threaded connection.
- The special diaphragm design ensures smooth opening and closing, preventing the formation of microbubbles.
- A special guide ring on the piston rod prevents lateral movement of the seat, which significantly extends the service life of the seal and reduces particle build-up.
