LN87 Cage guided regulating valve
High Precision
Globe Control Valve Globe valve are designed strictly on the basis of the IEC standard. They are the latest self-innovated modularized straight stroke control valve of SUPCON. We divide the trims into three modules, namely guide, control and seal module. We provide the best solution according to the function of each module and make action, control and seal more reliable.
Each index, linear, hysteresis, dead zone and leakage, for example, is full compliance with national standards.
Cage guided valve Note: For below measured results, take LN8100 top guide single seat valve (PN110) as an example.

Cage guided regulating valve Easy to maintain
The unique platform and modul design make it easy to remove and displace the parts without special tools, and moreover, easy to change the type of the valve only by changing few parts. A variety of material combinations is optional for the parts.
LN87 series Cage guided regulating valve are LN8 series pressure balance single-seat valve products, one of the three basic guide sleeve, pressure balance type single-seat valves, with separate sleeve structure, high-performance metal piston seal, has the good dynamic stability, high control precision, allow the pressure difference is big, the operating force is small, large flow capacity, a broader range of applicable temperature etc. Suitable for fluid control of harsh working conditions.
