What raw materials can Ruitu bromine extraction systems process?

Our bromine extraction systems are designed for seawater, bitter brine, salt lake brine, oilfield water, bromine-bearing industrial wastewater and concentrated brine from desalination plants. The process route is selected only after we review a laboratory analysis of your feed.

Do you supply single machines or complete plants?

Both. We supply individual machines such as salt washers, roller crushers, dryers, vibrating screens, belt conveyors and hot air furnaces, and we also deliver complete turnkey lines under an EPC contract.

What is included in your EPC service?

Water quality testing, site selection support, process design, project launch preparation, equipment manufacturing and procurement, packing and shipping, installation and commissioning, operator training, finished product production guidance, and output buy-back or decommissioning support where agreed.

Can your salt washing equipment produce food-grade salt?

Our salt washing machinery is used for both food-grade and chemical-grade salt. The achievable grade depends on the crude salt composition and the standard that applies in your market, so we design the washing, crushing, drying and screening stages around your target specification.

How do you support overseas installation?

Our engineers can be dispatched to site for installation and commissioning, train your operators, and stay involved until the line produces finished product at the designed daily capacity.

How do I start a project with Ruitu?

Send us your raw material analysis, target daily capacity, product specification and site information by email or phone. Our technicians will prepare a preliminary budget estimate and an economic benefit analysis based on your budget and expected output.

Product Description

Core Overview

The PTFE-lined electric butterfly valve is a high-performance flow control device designed for rigorous industrial applications involving corrosive media. It combines a robust cast steel or stainless steel body with a seamless virgin PTFE lining and disc, ensuring complete isolation of the metal components from aggressive fluids. Integrated with a precision electric actuator, it offers automated remote control for opening, closing, and flow regulation. This valve is ideal for chemical processing, pharmaceutical manufacturing, water treatment, and power generation industries where reliability, corrosion resistance, and precise automation are critical.

Core Advantages

Exceptional Corrosion Resistance

Full PTFE lining protects against strong acids, alkalis, and solvents, ensuring long-term durability in harsh chemical environments.

Precise Electric Control

Automated actuator allows for accurate flow regulation and remote operation, integrating seamlessly with PLC/DCS systems.

Zero Leakage Design

Tight sealing between the PTFE disc and seat ensures bubble-tight shut-off, preventing media loss and contamination.

Low Operating Torque

Optimized disc design and PTFE’s low friction coefficient reduce wear on the actuator and extend service life.

Versatile Installation

Compact wafer/lug design fits between standard flanges, saving space and simplifying maintenance in complex piping networks.

Frequently Asked Questions (FAQ)

Q What media are suitable for a PTFE-lined electric butterfly valve?

Due to the chemically inert nature of virgin PTFE, this valve is suitable for handling aggressive media including concentrated acids (hydrochloric, sulfuric, nitric), strong alkalis, organic solvents, and high-purity pharmaceutical fluids.

Q What is the difference between On-Off and Modulating electric actuators?

An On-Off actuator is designed strictly for fully opening or fully closing the valve, whereas a modulating actuator accepts a 4-20mA or 0-10V control signal to adjust the disc to intermediate angles for precise flow rate regulation.

Q What are the primary advantages of virgin PTFE over standard elastomer linings?

Virgin PTFE provides significantly superior chemical resistance, broader temperature stability (-20°C to +180°C), and lower friction compared to standard elastomers like EPDM or NBR, minimizing media sticking and prolonging service intervals.

Q What flange standards are compatible with these valves?

The wafer and lug valve bodies are engineered to clamp universally between standard pipeline flanges adhering to ANSI Class 150, DIN PN10/PN16, JIS 10K, and GB standards.

Q Can the electric actuator be operated manually during an electrical power failure?

Yes, the electric actuator comes standard with a declutchable manual handwheel or override mechanism, allowing operators to manually open or close the valve safely during power disruptions or emergency maintenance.

Q What ingress protection rating does the actuator offer?

The standard enclosure rating is IP67, providing complete protection against dust and ingress under water immersion, with an optional upgrade to IP68 for continuous underwater or severe outdoor conditions.
