  Balem 130 can perform as a multi-functional valve such as pressure reducing, pressure relief, constant flow, constant level, remotely On/Off, check, altitude, and pump control by selecting types of pilot valve to bring the best efficient outcome in water works & sewerage, industrial plant, chemical, fire service, shipbuilding sites. This valve can be used in various industries with 10kgf/㎠, ANSI 150 class, and pattern of globe and angle type.
   Balem 130 as the difference pressure action diaphragm valve efficiently using difference of pipeline pressure and is operated by diaphragm action according to pressure inside of the chamber and is designed to embody a various, accurate control. Balem 130 consists of 4 compartments. They are body assembly, diaphragm assembly, intermediate chamber and cover. Especially, the diaphragm is built with N.R, which is highly excellent intensity of nylon fabric, makes it safe to use. Also, theoretically calculated design, computer simulation, repeated test approval guarantee its ability and safety. All products are coated with epoxy coating of NSF/ANSI Standard 61 or Rilsan nylon coating approved by FDA provides hygiene and extends its life. Adapting flow adjusting assembly, valve position indicator, limit switch assembly such as additional features, can apply the system efficiently as performs a various functions with one valve.

▶ Technical Information

●  Rilsan Coating  

   Rilsan is obtained from the castor oil by polycondensation of laurylactame, available in granule form. Rilsan fine powder(Nylon 11), approved by FDA is using Hot dipping method to coat metals by providing nontoxic to human body, hygienic, and applicable to various sites such as Alkali, Oil, industrial solvent, LPG, Natural gas, Milk, fruit, and etc. Also, it proudly presents excellent anti-corrosion to sea water, and the surface coefficient of friction.

·surface hardness : Shore D 75
·Break strength : No damage on coating surface at 50Cm drop of 20N mateil metal (Thickness of coating
                   0.3mm)
·Treadwear : At “Taber” abrasimeter (Type CS 17, load 9.81N) loss of weight after 1000 turns 5-8mg.
              (“Excellent”) 30-40kV/mm (generally required satisfactory valve : 10kV/mm, min)
·Melting temperature : 184-186℃
·Flammability : “Self extinguishing” acc.

● Epoxy Coating   

   The standard epoxy coating of NSF/ANSI standard 61 applies for all valves. It has excellent chemical resistance to seawater, specific acids, bases, chemical and solvent, and provides hygienic water to users.
