The pneumatically operated NC stainless steel seal valves are angle valves and have a Y-shape in which the seat is placed at an angle. This ensures that the medium is minimally hindered in open position, resulting in low pressure loss and excellent flow rate. The air operated piston moves the Teflon seal trough a spindle to or from the valve seat. Seal valves are a popular choice for heavy-duty applications because they are suitable for high temperatures, reliable, durable and have a long service life, as well as requiring little maintenance. They can be used for liquids that come under the seat to prevent water hammer.
