Detailed Description

Square Body Needle Valves Male x Female are engineered for precise flow control and isolation in high-pressure piping systems. The square body design provides a rigid, compact structure that allows for stable mounting, easy wrench access, and alignment during installation. The male and female threaded ends enable secure connections to instrumentation, piping, or process equipment, ensuring leak-tight operation.

These valves are used in oil and gas applications such as connecting impulse lines, controlling flow to pressure transmitters, and isolating instrumentation for maintenance or calibration. The square body allows for easy integration into compact manifolds or tight piping layouts where space and alignment are critical.

Constructed to meet ASME B16.34 and MSS-SP-99 standards, the valves are rated for standard working pressures of 6000 psi, with optional higher-pressure ratings available. They operate effectively over a wide temperature range and are factory-tested for seat and packing leakage, ensuring reliable, consistent performance in demanding field conditions.
