RGV01-TF010203--Operation and Maintenance Manual DOWNLOAD

1. Dual Operation Mode for Fail-Safe Reliability
Electric Control: Equipped with a high-performance electric actuator enabling remote/centralized one-touch operation. Easily integrates into SCADA or DCS systems for on/off or modulating control, significantly enhancing process automation and efficiency.
Manual Override: An integrated handwheel on the actuator allows immediate switch to local manual operation during power failure, maintenance, or emergencies, ensuring system safety and continuity—a true double safety guarantee.
2. Non-Rising Stem Design for Compactness & Durability
Features a non-rising stem (NRS) design where the stem rotates without rising during operation. This keeps the overall valve height constant, requiring minimal installation space, making it ideal for valve pits, underground piping, or equipment-dense areas.
The stem nut is integrated within the gate and protected inside the valve body, shielding it from external corrosion and contamination, resulting in more stable operation and extended service life.
3. Reliable Gate Valve Sealing & Unobstructed Flow
The gate design provides a full-bore or reduced-bore flow path, offering minimal flow resistance and pressure drop when fully open, which enhances energy efficiency.
Precision-ground seat and gate sealing surfaces, coupled with a rigid wedge or flexible gate design, achieve bidirectional or unidirectional tight shut-off, with leakage rates meeting or exceeding standards like ANSI/FCI 70-2.

This article introduces a through-hole wafer butterfly valve featuring a split body design, PTFE seat, polished stainless steel disc, and ductile iron body. The through-hole mounting eliminates threaded lugs, allowing bolts to pass through the body and flanges for secure, cost-effective installation. The split body construction enables in-line maintenance and field-replaceable PTFE seats, while the PTFE seat provides superior chemical resistance for aggressive media. Ideal for chemical processing, pharmaceutical, petrochemical, water treatment, and desalination applications. As an LRQA-certified ISO 9001:2015 OEM/ODM manufacturer with over 15 years of export experience, Tianjin Worlds Valve Co., Ltd. offers fully customizable solutions to meet specific project requirements.
This article provides a material selection guide for 18-inch wafer butterfly valves used in water and wastewater systems. It explains why a ductile iron body, CF8M stainless steel disc, and EPDM seat form a balanced configuration for large-diameter water service. Key topics include material properties, installation best practices, common pitfalls, and maintenance tips. The article concludes with guidance on matching materials to specific applications and introduces Tianjin Worlds Valve as an OEM manufacturer capable of customizing valves to project requirements.
This article explains how OEM and ODM cooperation works with a Chinese valve supplier, focusing on customizable butterfly valves. It covers the differences between OEM and ODM, what can be customized (materials, dimensions, actuation, testing, branding), the step-by-step process, required buyer information, and the importance of standards and documentation. Tianjin Worlds Valve Co., Ltd. is presented as a direct OEM/ODM manufacturer with ISO 9001 (LRQA) certification, offering wafer, lug, flanged, U-type, PTFE/PFA-lined butterfly valves, customizable materials, and full documentation. The article concludes that successful OEM/ODM sourcing depends on an approved specification that can be reproduced consistently.
This article explores key growth regions and emerging opportunities for butterfly valves, covering MENA (desalination and water security), North America (infrastructure renewal), Europe (water resilience and compliance), and Asia-Pacific (urban and industrial expansion). It identifies three high-potential emerging applications–water reuse and desalination, district cooling and automated HVAC, and chemical/corrosive service – and explains how regional trends translate into real valve orders. The article also highlights Tianjin Worlds Valve Co., Ltd.'s OEM/ODM capabilities, including WRAS-approved potable water valves, PTFE/PFA-lined valves for corrosive media, and full customization across sizes, materials, and international standards.
