SWISS optio reducing valve for NO
The NO reducing valve at a glance:
- piston pressure reducing valve for gas mixtures containing nitric oxide (NO)
- preset working pressure and orifice for adjusting the outlet flow
- with high pressure gauge to display the cylinder pressure
- optional fine adjustment valve at outlet
- intended for clinical usage
The NO reducing valve is a preset piston pressure reducing valve for use with medical gas mixtures using nitrogen as the carrier gas and containing small amounts of nitric oxide (NO) for therapeutic applications. The working pressure of the NO reducing valve is preset according to the customer specification. The outlet of the NO reducing valve has an orifice for precise adjustment of the gas flow. The gas flow can be further controlled with an optional fine adjustment valve. This function can also be achieved using an additional internal flow regulator in the gas-consuming equipment.
The NO reducing valve is fitted with a high pressure gauge to display the cylinder pressure. It has a pressure relief valve that discharges radially. All metal parts of the NO reducing valve that come into contact with gas are stainless steel (INOX).
The NO reducing valve should only be installed by qualified technical personnel who are aware of the dangers and risks associated with the use of the gas mixture.
The NO reducing valve is certified based on norm EN ISO 10524-1. CE marking according to the Guideline for Medical Products 93/42/EEC.
