Notes:

1. G thread is the conventional thread, and ZG (PT), NPT and other threads can also be customized according to users´ requirements.
2. When the valve body is out of stock, replace it with the MJ11 globe valve body (the valve disc is manufactured according to the control valve´s disc). Please refer to the sample MJ11 series globe valves in Volume 4 for the external dimension.

T10 Series Threaded Type Manual Control Valve

The BEST T10 Series Threaded Type Manual Control Valve is designed for manual regulation of gas and liquid flow in industrial piping systems. Featuring a handwheel-operated structure and threaded connections, this valve provides a practical solution for applications requiring manual flow control.

Available in nominal sizes from DN15 to DN50, the T10 series supports different valve body and sealing material options to accommodate varying operating conditions. Its standard flow characteristic is linear, while an equal-percentage characteristic is available as a special option.

Key Features

• Manual Operation: Handwheel-operated design for manual flow regulation.

• Threaded Connection: Internal threaded connection for installation in compatible piping systems.

• Nominal Size Range: DN15 to DN50.

• Pressure Rating: Normal PN16; special pressure options of PN25 and 40 bar are listed in the manual.

• Flow Characteristics: Linear as standard; equal percentage available as a special option.

• Applicable Media: Gas and liquid.

• Leakage Class: Class IV for hard sealing and Class VI for soft sealing, as specified in the manual.

• Flexible Installation: Can be installed at any angle. For horizontal installation, the valve stem should be positioned vertically upward to help extend service life.

• Material Options: Forged steel A105, SS304, SS316 and SS316L valve body options are listed in the product coding and material tables.

Technical Specifications

Material and Temperature Options

The manual lists different temperature ranges according to valve body material and sealing configuration:

• Carbon Steel: The feature section lists a normal Va range of -29°C to 350°C and a special IIIa range of -29°C to 150°C.

• Stainless Steel: The feature section lists a normal IIIb range of -40°C to 150°C and a special IVb range of -40°C to 250°C.

• PTFE Sealing: Temperature applicability depends on the valve body material and configuration.

• Improved PTFE: Listed as a special sealing option for stainless steel configurations.

The actual allowable temperature must be confirmed against the selected body, sealing material and product configuration.
