Threaded Ball Valves

Detailed Information on Threaded Ball Valves

Threaded ball valves are the most preferred valve type for small and medium-diameter lines due to their compact structure and easy installation features. Since the spherical closing element is full-bore, it minimizes pressure loss and allows for the free flow of the fluid. PTFE-based sealing gaskets provide long-lasting performance even under challenging conditions.

Connection Options

• • Threaded (Female – Male)
• • NPT tapered thread
• • Double-sided female connection
• • Threaded + union connection options

Advantages

• • Quick and easy installation.
• • Minimum pressure loss with full-bore design.
• • High sealing performance thanks to PTFE gaskets.
• • Suitable for water, steam, gas, and compressed air lines.
• • Brass, stainless steel, cast iron, PVC, and carbon steel body options.
• • Precise on/off feeling in operation.
• • Ease of use in tight spaces with its compact design.

Material Specifications

• • Body: Nickel-plated brass, stainless steel, cast iron, PVC
• • Ball: Stainless steel or chrome-plated steel
• • Gaskets/Seats: PTFE, RPTFE, graphite
• • Cap/Bonnet: Brass or stainless steel
