Pressure Relief Valve Selection Guide

If there is no intermediate demand A (in the case of intuition with a large elevation difference)	If the intermediate demand is A (sometimes if the demand is singular to A)	In the case of a block system
If the supply pipe is long and the height difference is large, it is the safest and most efficient to install a general pressure reducing valve (model 132-010) in the middle. However, if there is a possibility that there is a possibility of generating electricity in a nearby area in the future, it is recommended to consider a pressure reducing and pressure maintaining valve (Model 132-030) with a pressure maintaining function at the front end. ※ Pressure reducing valve (Model 132-010)	If there is a demand in the middle and a lot of water is used in the sub-system, the area where there is a possibility of water outage at a high-altitude customer is a pressure reducing and pressure maintaining valve with a pressure maintaining function at the front end rather than a general pressure reducing valve (Model 132- 030) is the safest and most efficient. ※ Pressure reducing and pressure maintaining valve (Model 132-030)	When water is systematically supplied by compartmentalizing (blocking) the supply area, it is the safest and most efficient to install the Robosys Robocon valve (model 130-010). It can be stably added to an already operated system, and if a control system is required, the BALEM SCADA System is provided. ※ Robosys Robocon (Model 130-010)

If there is no median demand A			bidirectional control
Built-in battery	electronic	Real-time flow detection	bidirectional control
ㆍBuilt-in battery that can be used for 5 years ㆍStable supply of water to the secondary side by dividing high-pressure and low-pressure time zones through time setting	ㆍRequires external power supply ㆍ Section can be changed without limitation by external power control	ㆍFully mechanical operation ㆍ Automatically change section by sensing actual flow ㆍNo limit on number of changes	ㆍPrecise real-time bidirectional control by selecting the most efficient pressure for each time zone

Flow coefficient Kv or Cv = Q/√ΔP, Cv = 1.168Kv

Kv: Flow rate per hour Q (㎥/hr) at differential pressure 1 (kgf/㎠)

Cv: Flow per minute Q (Gal/min) at differential pressure 1 (PSI)

ΔP : pressure difference between both ends of the valve (kgf/cm2 or PSI)

epoxy coating

By applying NSF/ANSI Standard 61 epoxy powder coating to all valves as a basic specification, it has excellent chemical resistance to seawater, certain acids, bases, chemicals and solvents, and provides hygienic water supply to users.

Notes on product selection

One.	Check the flow performance of the product and select a diameter suitable for the required flow rate. If you select too small a bore, the supply flow will be insufficient, and if you select too large a bore, chattering may occur.

2.	Our products are segmented by function. If you want additional features, please contact us.
