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.

Custom PTFE-Lined Ball Valve Factory, Product

Brand: Ruitu Automation

Product origin: China

Equipment Type‌: A manually operated ball valve with PTFE lining on both the valve body and ball core. It controls the on/off of the valve by rotating the ball core through a handle.

Purpose‌: Used for controlling the on/off of fluid in pipelines. The manual operation is simple and reliable, suitable for scenarios involving the transportation of strongly corrosive media where manual control is required.

Advantages‌: The PTFE lining is resistant to strong corrosion, extending the service life of the equipment; the ball valve structure has low flow resistance, resulting in low fluid transportation loss; manual operation is simple and intuitive, making maintenance convenient.

Product Description

Core Overview

The PTFE-lined ball valve is a high-performance quarter-turn shut-off valve designed for handling highly corrosive and abrasive media in industrial pipelines. Constructed with a robust cast steel or stainless steel body fully lined with virgin Polytetrafluoroethylene (PTFE), it ensures complete isolation of metal components from aggressive fluids such as strong acids, alkalis, and organic solvents. The valve features a PTFE-encapsulated ball and reinforced PTFE seats, providing excellent sealing and low operating torque. It is widely used in chemical processing, pharmaceutical manufacturing, water treatment, and power generation industries where reliability, corrosion resistance, and zero leakage are critical.

Frequently Asked Questions

What media are PTFE-lined ball valves suitable for?

They are ideal for handling highly aggressive media, including strong acids, alkalis, corrosive salts, organic solvents, and toxic fluids commonly found in chemical and pharmaceutical plants.

What is the maximum operating temperature for these valves?

The standard operating temperature range for virgin PTFE-lined ball valves is from -20°C up to +180°C, depending on the working pressure and specific line conditions.

How is zero-leakage achieved in this design?

Zero leakage (ANSI/FCI 70-2 Class VI bubble-tight shut-off) is achieved via the combination of precision-machined PTFE seats and a seamless PTFE-encapsulated ball that ensures uniform sealing contact.

Can these valves be automated?

Yes. They feature a low operating torque design and can be easily configured with ISO 5211 mounting pads for direct coupling with pneumatic or electric actuators.

What connection types and flange standards are available?

Standard connection types include flanged ends conforming to ANSI, DIN, JIS, and GB standards, as well as threaded (NPT/BSP) options for smaller nominal sizes.
