A wafer ball valve is a simple, cheap, and space-saving way to control flow. You can trust it to be easy to use and work well.

How It Works

Operation Mechanism

You control a wafer ball valve by turning its handle. When you turn the handle, the ball inside the valve rotates. This ball has a hole through its center. If you line up the hole with the pipe, fluid flows through. If you turn the ball so the hole faces away from the pipe, the flow stops. This simple action gives you quick control over the flow.

The valve uses a stem to connect the handle to the ball. The stem design prevents it from blowing out under pressure. You get a safe and reliable operation every time. Some valves also have an anti-static device. This device stops static electricity from building up, which keeps your system safe.

Tip: Always turn the handle slowly. Quick turns can cause water hammer or pressure surges.

Flow Control

You can use a wafer ball valve to start, stop, or adjust the flow of liquids or gases. The valve works well for both on-off and throttling tasks. When you open the valve fully, you get almost no resistance. This means you can move a lot of fluid with little pressure loss.

Here is a simple table to show how the valve position affects flow:

Handle Position	Ball Position	Flow Status
Parallel	Hole open	Full flow
Perpendicular	Hole closed	No flow
Partially open	Hole angled	Controlled flow

You can use this valve in many places, such as water treatment, chemical plants, and gas lines. The compact design lets you fit it into tight spaces. You save space and get reliable flow control.

Wafer Ball Valve Features

Compact Design

A wafer ball valve fits where space is tight. Its small body goes between pipeline flanges. You do not need extra space for big parts. Many factories use wafer valves because they are slim. This makes them easy to put in small places. The valve is light, so you can move it without trouble. For example, VINCER’s Electric Italian Thin Ball Valves fit well in small spots. You get better flow control and fewer leaks.

• Fits well in small spaces
• Light and easy to move
• Slim shape helps flow control

Blow-Out Proof Stem

A blow-out proof stem gives you more safety. This keeps the stem from popping out when pressure is high. Rules like API 6D and ASME B16.34 say this is needed for safety. NTGD uses blow-out proof stems to make their valves safe and strong. You can trust the valve to stay in place, even if pressure jumps.

• Stops stem from popping out
• Follows API 6D and ASME B16.34 rules
• Makes the valve safer and stronger

Anti-Static Stem

The anti-static stem keeps you safe from static electricity. This is important with flammable liquids or gases. The stem has a special path that connects the ball, stem, and body. This lets static electricity leave the valve safely. It lowers the chance of sparks or explosions. Rules say anti-static resistance must be under 10 ohms for safety.

• Stops static from building up
• Lowers explosion risk with flammable stuff
• Lets electricity leave safely

Material Options

You can pick from many materials for your wafer ball valve. Some choices are stainless steel, carbon steel, or special alloys. The right material helps match the valve to your fluid and job. NTGD has many material choices, so you can find one that lasts and fights rust.

Safety Feature	Description
Antistatic Feature	Stops static charge that could cause fire with flammable stuff.
Firesafe Feature	Cuts leaks in a fire by using a backup metal seal.
Anti-Blowout Stem	Keeps the stem from being pushed out by pressure.
Emergency Sealant Injection System	Lets you seal both seats and the stem if there is a leak.
Double Block and Bleed Feature	Makes sure the valve shuts off to keep fluid away from other equipment.

You can count on NTGD wafer ball valves for strong flow and safe use in small spaces. The ANSI Class 150 rating shows how the valve works at different temperatures:
