JIS Gate Valve

JIS Gate Valve is a precision-engineered isolation valve manufactured to Japanese Industrial Standards, optimized for compact efficiency and reliable performance in diverse fluid systems.

Description

JIS Gate Valve is built to meet the specific dimensional and pressure requirements of the Japanese industrial market (JIS B2071 / B2081). Known for its space-saving design and high manufacturing precision, this valve provides an excellent seal for water, oil, and gas applications. Whether in cast iron, cast steel, or stainless steel, the JIS-standard construction ensures that the valve body can withstand significant stress while maintaining a lightweight profile compared to other international standards.

Features

JIS Compliance: Fully adheres to Japanese standards for flange dimensions (JIS B2220) and face-to-face lengths.
Compact Geometry: Often features a more streamlined body design, ideal for installations with limited space.
High Seating Accuracy: Precision-ground wedge and seat rings ensure leak-proof performance even at lower pressure differentials.
Versatile Material Options: Available in a wide range of alloys to handle both general utilities and corrosive chemical media.
Smooth Actuation: Handwheel and stem assembly are engineered for low-torque operation, reducing operator fatigue.
