Benefits Of Dual Plate
Check Valves
Product Characteristics
Water Hammer Prevention
Water hammer commonly occurs when
a valve is closed suddenly at an end of
a pipeline system, and a pressure wave
propagates in the pipe. Terofox Check Valves
have quick response by closing discs. It
decreases the frequency of water hammer
condition.
Non Slamming
When swing check valve is closed, the reversal
of fluids in the pipeline will slam the plates
(discs) against its seal, and would cause the
noise, shortening the valve service life in many
cases. Terofox Dual Plate Check Valves have
outstanding springs against the plates (discs)
to resist the reversal of fluids, causing the
plates(discs) to close slightly.
Simplicity Installation
Most of traditional swing check valves are
heavy and closed improperly. Also they take
more space than dual plate check valves.
Dual plate check valves are able to be
installed in any position, horizontal or vertical.
Why Choose Our Dual Plate Check Valves ?
Small space available, easy installation, quick closing to reduce
water hammer
Cost-efficient
Diversity of connections ( Wafer, Lug, Flange )
Wall thickness is according to B16.34 / API594
Quality assurance
High CV & Low Pressure Drop
Terofox Dual Plate Check Valves take
advantage of lower pressure drop with
functional operations.
Seat Leakage
Terofox Valves are generally tested in
compliance with international standard such
as API598 which has specified the permission
of leakage rate in 3 c.c./inch of bore /mm
( in hydraulic test ) by metal to metal check
valves. 700 c.c. leakage rate of permission by
air test.
Sour Gas Service
Terofox Dual Plate Check Valves are able
to meet the requirement of NACE MR0175
treatment.

Inspection and Test
Concentric Butterfly Valves, Rubber
1. Butterfly Valves shall be tested as per ANSI B16.34, MSS SP-61, API598, ISO 5208 Terofox would organize the
inspection according to API 598 if customers didn t require prior to order.
2. Butterfly Valves should be seated test as per MSS SP-61 or ISO 5208 with no leakage occurrence for resilient
seated.
3. If butterfly Valves are required by stem 17-4PH material, Terofox will test in compliance with MSS SP-61 or ISO

A butterfly valve is a valve which can be used for isolating or regulating flow, Operation is similar to that of a
ball valve, which allows for quick shut off. Butterlfy valves are currently favoured by customers due to lower
cost compared to other type of valves as well as bring lighter in weight. It means easy installation with simple
operation. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted
passage of the fluid. Terofox has several kinds of butterfly valves, each adapted for different pressure,
application and different usage.

The phenolic backed seat is non-
collapsible, streth resistant, blowout-
prood and easily replaceble.
The soft backed valve has a wider seal
section between seat and flange while
mounted, but soft backed seat is subjet
to distortion during installtion and closing
and is contributed to shaft leakage and
high torque.
