Our gate valves are of manifold tunrnings. The pitch orifice is locked by a solid leantsurfaced wedge between the supports.
Suitable for opening or locking duties, but inappropriate for flow cheeking; straight pitch with minimal load decrease.
Use: General duties, resins, oil and gas, steam and fluids of different levels of viscosity.
Our globe valves are of manifold turnings. Locking occurs by means of a conical disc which obtrudes the fluid flowing through the support.
Suitable for checking duties. Liquid or gaseous flow. Moderate load decrease.
Use: General duties, liquid, steam and gas.
Our needle valves are of manifold turnings. Locking occurs by means of a conical disc in the valve rod. Which obtrudes the fluid flowing through the pitch orifice.
Suitable for a fine checking of fluids; high load decrease.
Use: General duties, liquid, steam and gas.
Our check valves are automatic valves, independent of external control, and operate according to the flow or preassure direction in the pipe system.
Our check valves include ball, piston and swing types, which allow fluid flowing in a only direction.
Horizontal - ball or piston: Set only a horizontal position. Moderate load decrease.
Lid-top: Set either horizontally or vertically. Very low load decrease.
Vertical - ball: Set only vertically. Moderate load decrease.
Use: Resins, oil, steam and fluids of different levels of viscosity. Inappropriate for drygas dealing.
