PRV & Gate Valve Installation in A PDAM’s Pipe Chamber, Balas Klumprik

The replacement of a EN 1074-2 compliant NRS gate valve for a pipe chamber of PDAM Surya Sembada.

PDAM Surya Sembada Kota Surabaya promptly installed a pipe chamber along Jl. Balas Klumprik in the Wiyung District on Saturday, December 14, 2024. This chamber was built to accommodate various pipe accessories—such as a pressure reducing valve (PRV), a flow meter, and a gate valve—to help regulate water pressure and distribution in the Balas Klumprik area and its surroundings.

EN 1074-2 ductile iron flanged NRS resilient-seated gate valves, supplied to Surabaya, Indonesia.

A pilot-operated pressure reducing valve (PRV) in a water supply pipe chamber automatically lowers and stabilizes the incoming water pressure to a safe, consistent level for downstream distribution. This regulation protects pipes, fixtures, and equipment from damage due to excessive pressure while ensuring efficient, reliable water flow—even when the supply pressure fluctuates. Meanwhile, the gate valve, usually furnished with non-rising stem & resilient seat, provides a means to manually isolate the PRV and the connected piping, which is especially useful during maintenance or emergencies, ensuring that sections of the system can be safely shut off without affecting the overall water supply.
