Shut-off Seat Valve with Leak Detector

Information

NLD/NTD shut-off valve is a pneumatically actuated sanitary single seat valve designed to detect product loss in case of the seal failure. 

Information

NLD NTD Shut-off Seat Valve with Leak Detector

Information

Funktionsweise

The valve is pneumatically actuated by means of compressed air.
The valve is supplied with a NC single-acting pneumatic actuator, thus in case of air supply failure, the valve goes back to the safety position (closed valve). 
The detector is installed as NO (normally open), so that when the valve is closed, it lets the product out, thus giving a signal of leakage.
The seat is provided with two gaskets, between which a safety or detection chamber with a direct outlet to the exterior via the detector is formed. 
Compressed air must simultaneously be supplied to the actuator (to open the valve) and to the detector to close it and prevent any loss of product.
Small amounts of product may be lost at the moment of the valve actuation, an air flow regulator can be installed to synchronise the opening/closing times of the actuator/detector to minimise these losses.
