A Comprehensive Guide to Jewellok Ultra High Purity Diaphragm Valves

A Comprehensive Guide to Jewellok Ultra High Purity Diaphragm Valves

Introduction

In the realm of high-tech industries such as semiconductor manufacturing, pharmaceuticals, and biotechnology, maintaining ultra-high purity (UHP) in gas and fluid delivery systems is paramount. Contaminants, even at trace levels, can compromise product quality, yield, and safety. This is where ultra-high purity diaphragm valves come into play, serving as critical components that ensure hermetic sealing, minimal particle generation, and precise flow control. Jewellok Technology, a leading manufacturer based in Shenzhen, China, has established itself as a key player in this niche with its innovative range of UHP diaphragm valves. These valves are engineered to meet the stringent demands of precision industries, offering reliability, cleanliness, and performance that align with global standards like ASME and CE.

Jewellok's UHP diaphragm valves are designed for applications involving high-purity gases, aggressive chemicals, and sensitive processes. They feature advanced materials and construction techniques that minimize entrapment areas, facilitate purging, and maximize flow capacity. This guide provides a comprehensive overview of Jewellok's UHP diaphragm valves, covering their design, types, features, specifications, applications, and best practices for use. By delving into these aspects, we aim to equip engineers, technicians, and decision-makers with the knowledge needed to select and implement these valves effectively.

Design and Construction

At the core of Jewellok's UHP diaphragm valves is a commitment to material excellence and precision engineering. The body is typically constructed from 316L VIM-VAR (Vacuum Induction Melting-Vacuum Arc Remelting) stainless steel, a material renowned for its ultra-low inclusion content and superior corrosion resistance. This choice ensures the valves can withstand harsh environments while maintaining purity levels essential for semiconductor fabrication and other clean processes. The inner surface of the valve body achieves an exceptional roughness average (Ra) of 5 μin (0.13 μm), which minimizes particle adhesion and allows for complete cleaning of the flow channel.

The diaphragm itself is a standout feature, crafted from high-strength, corrosion-resistant alloys such as Hastelloy C-22 or cobalt-based superalloys (UNS R30003). This design optimizes cycle life, enabling the valve to endure over 100,000 operations without degradation. The diaphragm provides a hermetic seal, isolating the process media from the actuator and external environment, thus preventing contamination. Jewellok employs a fully contained PCTFE (Polychlorotrifluoroethylene) seat design, which offers excellent resistance to swelling, contamination, and particle generation. This seat material enhances helium leak test performance, with every valve undergoing rigorous helium testing before shipment to guarantee leak-tight integrity.

Assembly and packaging occur in high-cleanliness environments, adhering to protocols suitable for the semiconductor industry. This meticulous process ensures that the valves arrive ready for immediate integration into UHP systems, reducing downtime and contamination risks. Additionally, Jewellok's valves incorporate advanced spool designs for precise pressure control, with output fluctuations limited to ±1%, making them ideal for stable gas delivery.

Types and Models

Jewellok offers a diverse lineup of UHP diaphragm valves to cater to various operational needs, including manual, pneumatic, and electronic actuation options. The HD Series stands out as a flagship line, encompassing high-pressure pneumatic and manual variants.

The HD Series High Pressure Pneumatic Diaphragm Valve is engineered for demanding applications requiring pneumatic operation under high pressure and temperature conditions. It features a robust stainless steel construction and is optimized for ultrahigh-purity gas systems. A companion model, the HD Series High Pressure Manual Diaphragm Valve, provides manual control for scenarios where simplicity and direct operator intervention are preferred.

For lower pressure environments, Jewellok provides the Low Pressure Pneumatic Diaphragm Valve and Low Pressure Manual Diaphragm Valve. These models maintain the same high-purity attributes but are tailored for applications with reduced pressure requirements, such as laboratory gas lines or secondary distribution systems.

Additionally, Jewellok's High Purity Diaphragm Reducing Valves integrate pressure regulation with diaphragm sealing. These valves feature a double-seat structure and are available in configurations like SF (Standard Flow), HF (High Flow), and FC (Flow Control), with maximum flow rates ranging from 800 to 1500 SLPM (Standard Liters Per Minute). Connection options include rear seat mounting or panel mounting, enhancing flexibility in system design.

All models support customization, including OEM services and modifications based on specific designs. This versatility allows Jewellok to address unique requirements in gas pipeline engineering, from semiconductor fabs to biomedical research facilities.

Features and Benefits

Jewellok's UHP diaphragm valves boast an array of features that translate into tangible benefits for users. The hermetic seal and contamination-free construction ensure utmost purity, making them guardians of hygiene in aseptic production processes. The low surface roughness and fully swept flow paths minimize entrapment areas, facilitating efficient purging and reducing the risk of process media carryover.

Optional intelligent enhancements, like digital pressure gauges or IoT remote monitoring modules, enable real-time data feedback for predictive maintenance and process optimization. These smart capabilities are particularly valuable in high-tech fields where downtime can be costly.

In terms of performance, the valves offer precise pressure control across a broad range, from 0.1 MPa to 20 MPa, with high-pressure special models available for applications exceeding 1 MPa. The contained seat design improves leak performance and minimizes particle generation, contributing to higher yields in semiconductor manufacturing.

Looking ahead, Jewellok is investing in research and development to further enhance its ultra high purity diaphragm valves offerings. Future iterations may incorporate advanced IoT integration for predictive maintenance and enhanced data analytics, ensuring clients stay ahead in fast-evolving industries.
