Sun Hydraulics structures its product names (model codes) in a fixed format, making it easy to quickly understand key characteristics of the product. The model code is based on several parameters that describe the valve\u2019s function, size, control type, pressure range, material, and more. By interpreting the product name, you can understand quite a lot about the product, such as pressure setting, material, etc.<\/p>\n

Sun Hydraulics cartridge valves have a model code based on a seven-character code. The first four letters, for example RPGC, indicate the valve model. In this case, a pilot-operated pressure relief valve with a capacity of 200 l\/min. The third letter<\/strong> indicates the valve size.<\/p>\n RPC<\/strong>C 45 l\/min Each model is then followed by three suffix letters. For example, RPGC-LAN. The first letter<\/strong> depends on the type of control the valve has. Not all valves have all configurations \u2013 this depends on the valve function.<\/p>\n RPGC-L<\/strong>** Standard screw The second letter<\/strong> indicates the pressure setting range<\/strong>. Examples below \u2013 many more setting ranges are available, and it can also indicate the spring strength of the valve.<\/p>\n RPGC-*A<\/strong>* 7\u2013210 bar The third letter<\/strong> indicates the O-ring material<\/strong>. Standard is RPGC-**N<\/strong> Buna, but there is also RPGC-**E<\/strong> EPDM and RPGC-**V<\/strong> Viton.<\/p>\n Suffixes<\/strong> at the end of the code have the following meanings:<\/p>\n \/AP<\/strong> Stainless steel <\/p>\n Sun Hydraulics standard manifold bodies have a model code based on three letters<\/strong>. These valve bodies are also called 3lt<\/strong> (short for “3 letter”).<\/p>\n Suffixes<\/strong> at the end of the code have the following meanings:<\/p>\n \/M<\/strong> Aluminum <\/p>\n If the manifold bodies are made of steel<\/strong>, there are different surface treatments available:<\/p>\n \/S<\/strong> In the standard version, the manifold only have dewatering oil<\/em>, i.e. very limited protection during transport and storage. <\/p>\n Solenoid coil model codes consist of three digits<\/strong>, followed by three more digits<\/strong>, and possibly a letter at the end<\/strong>, for example 740-224D.<\/p>\n The first three digits<\/strong> represent the solenoid coil series:<\/p>\n \u2022 740-series<\/strong> is the newest and fits SUN\u2019s FLeX series<\/strong>, inner diameter is 16 mm. This series also has the option of high-power<\/strong> or low-power<\/strong> to match functionality to need.
