SIERRA model 7500 is an eccentric disc seated - double eccentric - butterfly valves. Valves body and discs are designed to provide minimal flow resistance. Precise tightness is inssured on both sides.

The model 1200 Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated automatic control valve. When installed in-line, they sustain minimum back- pressure thus prioritizing pressure zones, preventing line emptying, and pump overload

The model 1200R Pressure Relief Valve is a hydraulically operated, diaphragm actuated automatic control valve. When there is an excess pressure in the line the valve opens to flow out the excess water maintaining a constant pressure in the line and preventing the line from bursting.

SERIES 6400 is a single chamber aero-kinetic water air valve, which designed to prevent dynamic closure under higher air velocity.Valves has double orifice and perform three functions.
