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.

China PTFE-Lined Pneumatic Ball Valve Factories, Service

Brand: Ruitu Automation

Product origin: China

Equipment Type‌: A ball valve driven by a pneumatic actuator, 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 an air source.

Purpose‌: Used for controlling the on/off of fluid in pipelines. The pneumatic drive enables automated control, suitable for scenarios involving the transportation of strongly corrosive media where rapid opening/closing and automated control are required.

Advantages‌: The PTFE lining is resistant to strong corrosion and can withstand substances such as strong acids and strong alkalis; the ball valve structure has extremely low flow resistance, ensuring smooth fluid transportation; the pneumatic drive allows automated control, making operation convenient.

Frequently Asked Questions

Q1 What fluids and media are suitable for this PTFE-lined pneumatic ball valve?

Due to its virgin PTFE lining and encapsulated ball, the valve is engineered for highly aggressive and corrosive media, including strong acids, alkalis, organic solvents, and high-purity fluids used in chemical and pharmaceutical plants.

Q2 What actuator options are available for automated operation?

The valve integrates pneumatic actuation available in both Double-acting and Spring-return (single-acting/fail-safe) configurations, operating under a standard air supply pressure of 0.4 to 0.8 MPa.

Q3 What sealing standard and leakage rate does the valve meet?

The valve delivers bubble-tight sealing certified to ANSI/FCI 70-2 Class VI standards, ensuring absolute shut-off and zero leakage in hazardous fluid environments.

Q4 What are the working temperature and pressure limits?

The valve operates within a temperature range of -20°C to +180°C and supports pressure classes including PN1.6, PN2.5, and PN4.0 MPa across nominal sizes from DN15 to DN300.

Q5 What end connections can be selected for piping integration?

Standard flanged connections are available along with threaded and welded options to fit diverse pipeline requirements and international flange standards.

Q6 Why choose a full-bore PTFE-lined valve over reduced-bore options?

A full-bore design ensures that internal flow passages match the nominal pipe size, delivering high flow rates with virtually zero flow restriction and minimal pressure drop.
