Find My Check Valve
GPV® Wafer Check Valves feature an in-line spring assisted design to prevent flow reversal for liquids and gases. The edge guided disc and center guided stem ensure that the soft seated disc will always find its home and provide bubble tight shutoff while the 316 stainless steel construction provides superior corrosion protection.
