P/N WMP-SV-1.0″TC-USPVI-PP/EPDM $584 USD + shipping Accessories

We offer complete tank and vessel packages of carefully selected components, engineered and documented to meet the hygienic, aseptic and ultra-sanitary needs of the medical, pharmaceuticals, biopharmaceuticals and electronics industries. This includes all FDA, cGMP and USP VI requirements with proper material certifications and traceability.

Designs and materials are also available for less-demanding food, chemical and electronics production applications and for industrial blending system applications.

Available in a range of polymers and plastics, our high-purity valves present a number of advantages over stainless steel valves, including:

No corrosion
Lower cost
Lighter weight
Typically, negligible leaching (per multiple leachables/extractables studies.)
Higher chemical resistance
No thread seizing to metal

Inline valves are available for tank or vessel CIP piping and recirculation loops. These are offered in two designs:

Weir diaphragm
Ball

Design Details

Actuation: Manual and air-actuated (limit switch/position indicator is optional with automated valves)

Connection: Tri-clamp®

Sizes: ½” – 4”

Maximum temperature: Typical PE= 140 F and PP= 220 F and PVDF= 230 F

Maximum pressure: Most poly tanks are atmospheric design, so for any nitrogen blanket or pressure applications please consult www.wmprocess.com

CIP/SIP: All are CIP designs. SIP available, see further below.

Valve Materials

Valve bodies are available in FDA polyethylene (PE), Kynar® polyvinylidene fluoride (PVDF) or USP VI polypropylene (PP).

Diaphragm material options:

USP VI PP
EPDM
Silicone
Viton® fluoroelastomer
Teflon® (PTFE)

SIP/Autoclavable Valves

Valves composed of PVDF and/or PP may be sterilized in place (SIP). Autoclavable designs are readily available; please inquire. Many of our mix tanks are fitted with autoclave-style top-entry agitators. For more information, please see our autoclavable mixer offerings.
