Product Description

Technical Specifications

Valve Type	Flange ball valve	Structure	2PCS type
Standard	BS5351	Workmanship	Investment casting
Sealing direction	Single-directional	Sealing grade	Zero leakage

Characteristics

The PTFE, FEP, PFA and other fluoroplastics lining the inner cavity of the valve body have extremely strong chemical stability and can withstand almost all strong corrosive media such as hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, strong alkali, organic solvents, strong oxidants, etc.

Compared to stainless steel ball valves, its corrosion resistance range covers strong oxidizing and acidic media that stainless steel cannot cope with.

Key Advantages

1. Super strong corrosion resistance: Fluoroplastic lining layer can withstand almost all strong corrosive media, far exceeding stainless steel performance.

2. Smooth flow channel & anti-scaling: High surface smoothness and low friction coefficient prevent impurities from adhering, ideal for viscous slurries.

3. Compact & Easy Maintenance: Flange connection allows easy disassembly. Wear-resistant lining ensures a long service life with minimal maintenance.

Frequently Asked Questions

What are the primary lining materials used in these ball valves?

The valves typically use high-performance fluoroplastics such as PTFE, FEP, and PFA, which offer exceptional chemical stability.

Can these valves handle extremely acidic media?

Yes, they are specifically designed to withstand strong corrosive media like hydrochloric acid, sulfuric acid, and even hydrofluoric acid, which often pose challenges for standard stainless steel.

What is the operating temperature range for these lined valves?

The applicable temperature range is generally between -20°C and 120°C, depending on the specific fluoroplastic material used.

How do these valves prevent pipeline scaling?

The fluoroplastic lining has a very low friction coefficient and high surface smoothness, which makes it difficult for impurities to adhere to the flow channel.

Are these valves suitable for viscous media?

Yes, the smooth flow channel and anti-scaling properties make them ideal for chemical slurries and other viscous fluids containing particles.

What type of connection and operation is standard?

These valves typically feature a flange connection for easy installation and are operated via a manual handle for reliable control.
