A pressure reducing valve (PRV) takes water at a higher, varying inlet pressure and delivers it at a lower, steadier outlet pressure. Zoloto's compact PRVs work on the line pressure alone, with no external power, and accept up to 25 bar upstream with a 90°C working limit. The forged brass 1040B covers 15 mm to 50 mm and the bronze 1040A covers 65 mm to 100 mm. Both have female threads to IS 554 / BS 21 / ISO 7, hot forged brass trim and food grade rubber O rings.
Both PRVs have a tapping for a 1/4 inch BSP pressure gauge, so the outlet pressure can be set and checked. Choose the valve for the flow and the outlet pressure you need, not only the pipe size; FPS can help select and set it on site.
A safety relief valve does a different job: it stays shut until the pressure reaches its set point, then opens to let the excess out. Zoloto's spring loaded relief valves have a male screwed end to IS 554 / BS 21 / ISO 7, metal to rubber seating, a set pressure range up to 10 kg/cm²g and an 80°C limit, from 15 mm to 50 mm, in open discharge (1094) and enclosed discharge (1094A) types. FPS supplies, installs and sets these valves in Bhopal and across Madhya Pradesh.
