• Valves

Lama’s Globo (globe) valves have mainly been designed for use in self-cleaning systems. They can also be used as three-way hydraulic units, making it possible to make water flow to one or the other of two sectors.


They have small-sized bodies, but accept water at a high flow rate. They have an axially-mounted stainless-steel stem that serves as a guide for the main opening and closing manoeuvres. The stem also controls drainage during filter cleaning operations. The stem supports a membrane, which is used to control the flow of water towards the filter or to the drainage. This membrane is “globe” shaped, allowing it to fit perfectly inside the valve’s cover. This allows a maximum flow to be achieved with minimum load loss. A vulcanised rubber valve is connected to the end of the stem, used for controlling the drainage of dirty water out of the valve.


The sealing cover is fastened to the valve body using stainless steel bolts.


The valve closing operation is carried out in two clearly differentiated stages: the first is quick and the second is slower, allowing the water hammer effect to be prevented.


The system operates with a significant balance, as all manoeuvre changes are made around the geometrical stem of the valve – in this case the metal globe; this quality means that the system is not thrown out of balance, as there are no hydraulic forces.


Its plastic version (glass fibre reinforced polyamide), Globo Plastic solves typical problems related to more corrosive types of water. It is a valve with excellent advantages, which can be used as a cleaning device for the most demanding of filters. These qualities make it the most versatile out of the entire range of cleaning valves on the international market.
