Dual Plate Check Valve with S.S. 304 Disc PN 1.6

 

Product Overview

The Poline PN16 Dual Plate Check Valve with SS304 Disc – Wafer Type is designed for automatic backflow prevention in water, HVAC, fire fighting, utility, and industrial pipeline systems. Manufactured as per API 594, this compact wafer type valve saves installation space while delivering dependable check valve performance.

The valve uses spring assisted dual plates for rapid closing action, helping reduce reverse flow and minimizing water hammer effects. Its cylindrical body distributes stresses uniformly, while the streamlined internal flow path offers low pressure drop and better operating efficiency.

The SS304 stainless steel disc provides excellent corrosion resistance, longer service life, and suitability for water and moderately corrosive service conditions.

Frequently Asked Questions

1. What is a dual plate check valve?

A dual plate check valve uses two spring-loaded plates that open during forward flow and close automatically when flow reverses.

2. Why choose SS304 disc?

SS304 stainless steel offers better corrosion resistance than standard ferrous materials.

3. What is the advantage of wafer type design?

Wafer type valves are compact, lightweight, and easy to install between flanges.

4. What does PN16 mean?

PN16 indicates a nominal pressure rating of 16 bar.

5. How does it reduce water hammer?

The spring-assisted fast closing mechanism reduces reverse flow shock.
