Even under the condition of maximum rated pressure throttle can maintain the stability of the high, inside the valve components after table and hardening treatment, with long service life.
Seat leakage can meet ANSI standard level IV, STH is low and drain valve is a kind of pressure balance type valve, the valve body fluid channels in an s-shaped streamline, large flow capacity.
Regulator by bulky porous sleeve as the guidance, with large output force of CS cylinder piston executing structure, this valve can meet most of the general control of the use of the venue.
the valve has the following advantages:
1. Suitable for saturated water evaporation volume expanding requirements, reduce the fluid velocity, sleeve tertiary throttling, channel throttling area expanded step by step, reduce the fluid inside the valve components.
2. Fluid throttling face and sealing surface separately, components in the valve surface hardening treatment, high hardness, scouring resistance, long service life.
3. Regulating valve shuts rigor, metal seat leakage standards can achieve ANSI B16, 104 - 1976 Ⅳ level.
4. The structure of the components used in the valve pressure balance type, reduce actuator volume.
