Mitos FREE FLOW® Valve Teq Speqs

Elements are available in three materials: platinum-cured silicone, STA-PURE®, and CHEM-SURE® tubing. STA-PURE and platinum-cured silicone elements feature molecularly bonded molded silicone ends with integrated gaskets. CHEM-SURE elements feature 316L stainless steel crimped ends. For custom elements such as manifolds, sampling systems and continuous tubing, please contact your sales representative for details. Elements can be cleaned and sterilized by SIP/CIP and autoclave.

STA-PURE and CHEM-SURE elements are rated for 60 psig line pressure and 40 psig bar steam conditions. Silicone elements are rated for 30 psig steam conditions.

Valve Element

Each valve tubing element is shipped in sealed virgin polyethylene with a label denoting part number, lot number and description. A Certificate of Conformance is included with each shipment certifying that each element passes USP Class VI, cytotoxicity, physicochemical and visual inspection tests.

Certification & Packaging

The Mitos FREE FLOW Valve is designed specifically for the biotech industry. Its stright-through bore and peristaltic pump action eliminate turbulence to significantly reduce shear in the process line.

Cycle TestingExtensive open/close cycle testing has been performed on the FREE FLOW valve with the following results:

Ambient > 5,000,000 cycles40 psig steam > 40,000 cycles

BodyAll metallic components are 304 stainless steel. Valve sealing anvils are Techtron PPS polymer.

ActuatorPneumatic actuators feature springs of 17-4PH stainless steel and fasteners of 18-8 stainless steel. The air inlet line is a 1/8” NPT connection. The seals are either Viton or EPDM, depending on application. Stem guides are PEEK. GE silicone gel is used for lubricant and the piston stop is PVDF.

Standard manual actuator inserts are PVDF to provide mechanical strength and wear resistance. Mitos also offers a 10% glass-reinforced PTFE insert for customers sterilizing the valve by autoclave or cleaning by chemical soak.

Mitos FREE FLOW™ Valve Mitos FREE FLOW™ Valve

How It Works

The Tubing Element

Element Materials

Mitos Technologies' patented FREE FLOW™ valve is the only valve

designed specifically for the biotech industry. Available in stainless

steel or titanium, each FREE FLOW™ valve has a tubing element with a

single-wetted surface that eliminates seams, crevices and entrapment

areas, making it the cleanest valve in the industry.

The simple action of the Mitos FREE FLOW™ valve mirrors that of a

peristaltic pump. When activated via a pneumatic or manual

actuator, the flexible tubing element inside the body is squeezed

shut. When reopened, the element presents a completely

unobstructed flow path for fluid transfer. This straight-through

bore significantly reduces shear in the process line and allows full

drainage from any position, eliminating the need for complex

installation.

All FREE FLOW™ tubing elements have molded tri-clamp ends with

integrated gaskets to reduce seams between gasket faces,

providing unsurpassed cleanability via SIP/CIP or autoclave. The

standard element for the Mitos FREE FLOW™ valve is STA-PURE®

tubing, a unique composite of platinum-cured silicone and Teflon®.

Platinum-cured silicone elements are also available for manifold or

single-use applications. For added chemical resistance, elements

can be made from CHEM-SURE™ tubing.

STA-PURE® Element

- Successfully tested for millions of

open/close cycles at 50 psig line

pressure

- Withstands the toughest

clean-in-place/steam-in-place

(CIP/SIP) conditions

- Proven to perform well under 40 psig

steam conditions

CHEM-SURE™ Element

- Endurance benefits identical

to STA-PURE® tubing

- Handles nearly all

aggressive chemicals

- Operates over 50 times

longer than any other

fluoroelastomer tubing

Silicone

- Perfect insert for single-use

applications

- Lower cost option for

moderate endurance and lower

pressure ratings

- Fully SIP capable at 30 psig

steam conditions

Change out the Product Contact Surface in Seconds

The QR™ series FREE FLOW™ valve offers the same benefits of the

original lock-in body style, but features a side hinge to make

frequent element change-outs faster and easier. Now disposing of all

product contact surfaces takes only seconds. After removing the

valve from the process line (1), simply release the QR Locking Screw

(2), open the valve (3) and remove the element (4). To ready the

valve for operation, insert a new element, close the valve and clasp

the QR Locking Screw.

4Ideal for Continuous Tubing

The QR series is ideal for placement on continuous tubing

configurations such as manifolds and sampling systems. It is

the only method available for closing off tubing with a 1" ID.

Instead of attaching the valve by sanitary tri-clamp

connections, the valve body can be placed directly onto the

system with the continuous tubing acting as the valve

element. Thus, installation and removal of the valve can be

performed without disrupting the process line.
