Single-seat control valve (pneumatic)
Product Overview
One of the two basic product types of pressure-unbalanced single-seat valves, featuring a top-guided plunger valve core, floating clamping sleeve, self-centering seat structure, and modular design. It boasts a large flow capacity, high adjustment accuracy, wide adjustable range, and the ability to control even minimal flow rates. Its simple and reliable structure, excellent sealing performance, and ease of field maintenance make it suitable for applications with low pressure differentials and high requirements for seat leakage and control accuracy.
