PPR pipe fittings in the valve there are many, such as ball valves, globe valves, gate valves and so on. As a variety of PPR pipe, valve parts have different structures, composition materials, to withstand pressure, so a variety of valves can be different aspects of classification:
According to the structure of the classification: all kinds of valves have different forms of structure, such as cut-off valve with DC, angle, straight type, gate valve wedge, parallel and so on.
According to the valve material classification: a variety of valve body generally cast iron, cast steel, copper manufacturing, seat with copper, alloy, plastic or stainless steel.
Nominal pressure classification: According to the nominal pressure is divided into vacuum valve, low pressure valve, medium pressure valve, high pressure valve and high pressure valve.
