Note Fluoropolymers are high molecular weight resins, so permeation will always occur, especially under the following three conditions: low temperature (40゜C orlower), high pressure (0.8 MPa or higher), and high permeation chemicals (hydrochloric acid, hydroﬂuoric acid, bromine, organic solvents, and mixturescontaining additives). However, especially when these three conditions are combined, permeation may occur rapidly, so please contact us in advance.

TypeA

VALFLON™ Straight Hose（PTFE）

This is the ﬂexible hose with improvedpressure resistance, heat resistanceand ﬂexibility by adding stainless steel
wire blade and reinforced spring to
VALFLON™ straight hose.
●This is for general purpose and available
at low cost. Also, there is hardly any liquid
pool inside, and it is easy to clean.

TypeBThis is a ﬂexible hose with optimum
ﬂexibility by adding stainless steel
wire blade to VALFLON™ Pliable Hose.
●Since the hose can achieve thebending radius of up to about 3 to 4
times more than the hose internal
diameter, it is ideal for use in locations
with high vibration or in locations where
frequent part changes are needed.
●To get the equivalent size of innerdiameter, it adopts 1 over size hoses.

VALFLON™ Pliable Hose（PTFE）
Wire braid SUS304

TypeC

This is a ﬂexible hose with moderate
ﬂexibility, pressure resistance andheat resistance by adding stainlesssteel wire blade to VALFLON™
TOUGHLEX Hose.
●Liquid pooling rarely occurs in thishose by controlling unnecessary
curvature factor and adding a slightslope.

Please keep the gasket tightening stress at 15MPafor liquid, and at 20MPa for gas. Please avoid excessive
tightening over 30MPa since it could cause a damage
in the gasket and ﬂare area.
The gaskets' initial tightening stress could go down due
to stress relaxation including the ﬂare area; therefore,
please make sure to re-tighten the gasket at below timings.

Spray Ball™
Spray Ball™
VALQUA №7FZ1Spray ball is used for cleaning tanks such as reaction tanks, stirring tanks, and storage tanks. Since the spraying position is designed according
to the customer's tank nozzle orientation, eﬃcient cleaning is possible in a short time and the consumption of cleaning liquid can be suppressed.

The exposure area is a ﬁxedtype
spray ball made of VALFLON™
（PTFE）and connects to thenozzle in the upper part of thecan body in ﬂange shape.

The pressure of the cleaning
liquid is pressured at 15 to
20m（liquid column）. If there isnegative pressure inside thecan, please be aware that,unless the cleaning liquid isinserted gradually and thenegative pressure is resolved
before pressurizing, the sprayball will break due to water
hammer phenomenon.

If the can body is in special shapeor there are restrictions to attaching spray balls, we will create
an individual design based on
the standard dimensions.

Rotary Spray Ball™
Rotary Spray Ball™
VALQUA №7FZ1-R
Rotary Spray Ball is the product which is developed for medical, chemical, food productindustries or other.
The spray head portion of this product rotates in a vertically inverse manner, making it
possible to wash parts that are prone to being a blind angle, and to evenly wash the insidesof tanks.
It can be chosen from 3 types（50A, 80A, 100A）to meet all demands.

Since the cleaning water itself controls theball rotation, there are no parts for rotation
inside the product. It is extremely simple
structure.
It is easy to maintain because the spray ballis Three-Body-Structure（top-bottom headand body）and is made from PTFE（highchemical resistance）.
Washing range (Spraying range)
Head angle is upward 50˚sideways 180˚
downward -50˚

The operating liquid pressure is basicallyset for 0.15MPa.
Pressure setting range（0.1MPa to 0.2MPa）can be changed.
The amount of washing water can bechanged.

Even at low pressure, we can clean eﬃciently
because the spraying pattern makes astraight bar ﬂow.
