Frequently Asked Questions
What does "soft seated" mean, and what are its advantages?
Soft seated means the valve seat is made from PTFE or RPTFE polymer material, rather than metal. This design achieves ISO 5208 Rate A bubble-tight shutoff (zero measurable leakage) and operates continuously from -40°C to +180°C, requires lower operating torque, and delivers longer service life. It is ideal for clean media including water, natural gas, oil, and process chemicals that do not contain abrasive particles.
What does JIS B2011 10K / 20K mean, and which projects specify it?
JIS B2011 is the Japanese Industrial Standard for metal ball valves. 10K and 20K refer to the pressure rating in kgf/cm² — approximately 1.0 MPa (145 psi) and 2.0 MPa (290 psi) respectively, comparable to ANSI Class 150 and Class 300. JIS-specification valves are commonly required in Japanese EPC projects, and petrochemical or power plants across Southeast Asia, South Korea, and Japan where engineering firms follow Japanese standards.
What is the lead time, and can you accommodate custom specifications?
Standard sizes (NPS ½" to 8", 10K / 20K) are available in 4–6 weeks. Custom alloys, actuated packages, or witness inspection orders typically require 8–12 weeks. OEM private labeling and ITP documentation are available for EPC projects. Contact our team for a formal quotation.
