Diaphragm Valves

LPC14 Sanitary Diaphragm Valve

LPC14 Sanitary Diaphragm Valve is a precision-engineered flow control component featuring a crevice-free, self-draining architecture designed to maintain absolute sterility and prevent cross-contamination in critical processing environments.

Product Description

Engineered specifically for stringent hygiene applications, the LPE11 Sanitary Diaphragm Valve utilizes a flexible elastomeric membrane to physically isolate the process media from the upper actuation mechanism. Constructed from premium 316L stainless steel with an electropolished interior finish, this valve eliminates dead legs and fluid stagnation zones. Its streamlined, straight-through flow path facilitates seamless integration into CIP (Clean-In-Place) and SIP (Steam-In-Place) systems, ensuring compliance with rigorous GMP and FDA standards for aseptic processing.

Key Features

Aseptic & Crevice-Free Design: Features a smooth, self-draining flow path with an ultra-low surface roughness (Ra ≤ 0.4 µm) to prevent microbial harborage and ensure zero product retention.
Complete Media Isolation: The robust elastomeric diaphragm acts as a dynamic seal, completely separating the fluid pathway from the actuator to eliminate external leakage and contamination risks.
CIP/SIP Compatibility: Optimized for rigorous cleaning and sterilization cycles, capable of withstanding high-temperature steam sterilization without compromising seal integrity.
Regulatory Compliance: Manufactured with FDA-approved, USP Class VI compliant wetted materials, ensuring safety for food, beverage, and pharmaceutical applications.
Versatile Hygienic Connections: Available in Tri-Clamp, butt-weld, and threaded configurations to meet diverse international sanitary piping standards (DIN, 3A, ISO, ASME BPE).

Typical Applications

Biopharmaceutical Manufacturing: Aseptic fluid transfer, bioreactor feed lines, and sterile filtration systems requiring zero-dead-leg valves.
Food & Beverage Processing: Hygienic handling of dairy, craft brewing, fruit juices, and viscous syrups to prevent bacterial growth.
Purified Water Systems: Critical flow control in WFI (Water for Injection) and purified water generation loops.
Cosmetics & Fine Chemicals: Contamination-free processing of sensitive personal care products and active pharmaceutical ingredients (APIs).
