SF / Sure Flow Equipment Check Valves

Cole Industrial and Technical Supply Company is an authorized distributor of SF / Sure Flow Equipment check valves. These valves are ideal where space is a limiting factor, and can be used in both vertical and horizontal positions.

Mueller Check Valves

These Silent Check Valves have been re-designed in order to offer better flow, lower pressure drop and improved cost efficiency. Designed with compact springs, the valve prevents flow reversal to eliminate water hammer, vibrations, system surges and noise. These units can be installed horizontally or vertically

Wafer – Compact Design

The 90 M wafer check valves are suitable for normal liquid, air, and gas applications. These units are available in ductile iron, bronze, carbon steel, and stainless steel, all with stainless steel trim as a standard.

Wafer – Standard Design

The 90 M wafer check valves are suitable for normal liquid, air, and gas applications. These units are available in ductile iron, bronze, carbon steel, and stainless steel, all with stainless steel trim as a standard.

Globe – Flanged

Globe Style Silent Check Valves can be installed in horizontal or vertical flow. Each valve is 100% tested in accordance with ANSI, API and MSS standards.

Double – Disc

The Sure Check valves are designed for horizontal and vertical flow applications. Units are available in cast iron, ductile iron, carbon steel, stainless steel and other alloys.

Globe – Screwed

All steel, stainless steel and alloy models conform to API 594 and API 6D specifications. The Sure Check valves are designed for horizontal and vertical flow applications. Units are available in cast iron, ductile iron, carbon steel, stainless steel and other alloys.

Grooved End

These check valves are installed quickly with just two pairs of compression couplings and four bolts and nuts. The specially designed torsion springs exert a lifting motion on the discs to prevent excessive wear of the “heel” area of the seats. On site service may be done without special tools. The independent, dual shaft design allows interchangeability of shafts. The stop shaft stabilizes the discs during high flow rates.

UL Rated

The extremely short fact to face dimension and compact design of this check valve allow installation and service in tight spaces. The specially designed torsion springs exert a lifting motion on the discs to prevent exessive wear of the “heel” area of the elastomer seats. On site service may be done without special tools. The independent, dual shaft design allows interchangeability of shafts. The stop shaft stabilizes the discs during high flow rates.

Chexter

The contoured disc of the Chester lifts easily off the seat to open the valve. The aifoil design of the disc allows it to “float” on the flow. Rugged disc stops built into the body position the disc for optimum flow characteristics. Large body cavity helps minimize flow restriction. The valve functions smoothly and silently in both horizontal and vertical up-flow lines.
