NT Pinch Valves
The NT and NT/AP Series valves offer a simple and safe way to control the flow of material in a pipeline. Only the tubular diaphragm (hose) comes into contact with the fluid, thus increasing the life of the other components. Due to the flexibility of the tubular diaphragm, the system will always be completely closed, even in the presence of solid materials. For this reason, there will be no pressure losses or accumulation of materials inside the valve, facts of extreme
importance when operating with food products, fluids with large amounts of suspensions and minerals, among others.
Operational Parameters
Working pressure: ___ up to 17kg/cm2 (Room temp.)
Gauges: ___ from 1/2” ~ 24
Temperature: _____________________ Natural rubber diaphragm: 80ºC
Synthetic rubber diaphragm: 90ºC
Synthetic rubber diaphragm: 90ºC
Project Features
- Total absence of gaskets
- Positive closure even on solids.
- Up to 8” diameter gauge, NT valves are supplied in a fully closed construction with internal parts in nodular cast iron, steel stem and external body in cast iron or aluminum (optional); from diameter 10” to diameter 16” the valves are supplied in the same construction materials, but in open execution; from diameter 18” to diameter 24”, they also use the same construction materials in open execution but with actuation by means of a built-in reducer.
- NT/AP valves are supplied in a fully closed construction up to a diameter of 2.1/2”; from a diameter of 3” to 16” the execution is open, with valves with a diameter of 16” and above being actuated by means of a built-in reducer.
Advantages
- Free passage, without obstructions.
- Zero pressure drop.
- No mechanical parts other than the diaphragm in contact with the controlled product.
- Long lasting under severe conditions.
- Only one wear component – the tubular diaphragm (hose).
- Quick and simple maintenance.
- They are cast and are much more resistant, unlike other brands, which are made of laminates or welded and are more susceptible to twisting and breaking.
Applications
- NT and NT/AP valves are used in applications in different segments such as the chemical industry, mining, ceramics, water and wastewater treatment, offshore platforms, cement and occasionally in the food industry (with sanitary rubber hose), among others.
