SAYTAR-70 — Piston Pressure Reducing Valve
The BARIQ SAYTAR-70 is an automatic piston-operated pressure reducing valve designed to reduce and stabilize downstream pressure to a preset value in water distribution pipework. Its epoxy-coated ductile-iron body is suitable for indoor and outdoor systems, with large internal passages designed to limit flow resistance, vibration and pressure loss.
