3. Features

Installation between Flanges

PAN Check Valves are designed to be placed between flanges.

No water hannaering effect

There is no water hammering effect since the valve is closed by spring before water backflow takes place.

Malfunction Free

PAN Check Valves can be used at least for five years without maintenance under general conditions.

Common users can do maintenance and repair work easily.

Thin, Small and Light Structure

PAN Check Valves have much shorter length and lighter weight then those of swing or lift check valves because the disc stroke is short and body has no flange.

Air Tight Precision

PAN Check Valves ensure tight sealing between disc and seat surfaces since they are lap-machined. The operation is smooth and the contacting surfaces of disc and seat wear very little.

Either Horizontal or Vertical Installation

PAN Check Valves can be horizontally or vertically installed because of their spring compression structure. They can also be installed at the vertical downflow sections.

No external Leakage

Pan Check Valves have no external leakage since there is no machinning holes from outside

General Application

PAN Check Valves are designed for general purpose applications, and can be used instead of swing or lift check valves.

Free Alteration of Openning Pressure

Alteration of openning pressure is available upon consumr's request
