High pressure reducing and regulating valves

■ Suitable for initial pressures up to 2,400 psi; maximum recommended delivery pressure is 500 psi; minimum 40 psi.
■ Type LS-1 is furnished with a metal seat piston and cylinder particularly designed for high or low temperature and high pressure drop applications.
■ Type LS-2 is furnished with a Teflon seat and balanced piston design for applications requiring higher capacities and/or tight shutoff. The balanced design assures close control regardless of inlet pressure fluctuations.
■ Type LS-3 is furnished with a modified cylinder and no strainer screen for applications involving heavy or high viscosity fluids.
■ Type LS-4 is constructed for cryogenic service to -320°F.
