Applications
The DP1103 pressure reducing valve is used in fluid transfer networks to reduce and stabilise the pressure to an adjustable set point. According to Tecofi, the fluids are water, waste water and compatible non-compressible liquids.
Working conditions and installation
- Maximum inlet pressure: 25 bar.
- Adjustable downstream pressure: 1 to 5.5 bar (sizes 1/2″ to 1″) and 1 to 6 bar (sizes 1″1/4 to 2″); factory pre-adjusted to 3 bar.
- Working temperature: 0 °C to +80 °C.
- Construction: piston with compensated seat, compact; range DN15 to DN50.
- Install in a horizontal position.
- Two 1/4″ gauge ports, one on each side of the body, for checking the outlet pressure.
- Female/female threaded connections according to ISO 228 (equivalent to DIN EN ISO 228 and BS EN ISO 228).

FAQ
Frequently asked questions about DP1103
How many bar can the Tecofi DP1103 reduce the pressure to?
The downstream pressure is adjustable from 1 to 5.5 bar for sizes 1/2" to 1" and from 1 to 6 bar for sizes 1"1/4 to 2". It is pre-adjusted to 3 bar at the factory; the maximum inlet pressure is 25 bar.
Which fluids and temperatures is the DP1103 for?
Tecofi lists water, waste water and compatible non-compressible liquids, with a working temperature of 0 °C to +80 °C. The passport does not cover gas or steam; send an enquiry and CAD will confirm with the manufacturer before you choose.
How is the DP1103 installed, and how is the downstream pressure monitored?
Install it in a horizontal position; both ends are female threaded to ISO 228. The body has two 1/4" ports, one on each side, for a pressure gauge on the outlet while you set it.
How do I choose the DP1103 size?
It comes in DN15 to DN50 with Kv from 3.6 to 18 (see the Kv table). Send the flow rate together with the inlet pressure and the required downstream pressure and CAD will help with the size.
What do I send to get a quote for the DP1103?
Send the fluid, flow rate, inlet and downstream pressure, temperature, pipe size and quantity. CAD quotes within 24 working hours.
