ANGODOS MNZ is a flanged check valve with multi-orifice

ANGODOS MNZ is a flanged check valve with multi-orifice system that will automatically close by the effect of a speed reduction. It consists of a body made of two conic parts made of welded Steel or ductile cast iron. This parts of the body flange a multi-orifice disc made of stainless Steel which is the base for the closing. The body also includes Windows for maintenance works and optionally the installation of a by-pass system. The nozzle are completely vulcanized of EPDM (other elastomer available for every kind of fluid) assuring an uniform seat and avoiding critical leaking by pressure discontinuities at the sealing area. The nozzles will move always guided by the use of shafts in the fluid direction. The multi-nozzle system will automatically close the valve by a reduction or change of speed and direction, this closing will happen fast due to the assistant of the resort installed which also allows the valve to work in any position. Using this system the nozzles will move just 15mm so the valve will sudden close silently, avoiding slams and vibration.

ANGODOS AG1-SV is a full bore butterfly valve with flanged body and over-speed automatic closing system

ANGODOS AG1-SV is a full bore butterfly valve with flanged body and over-speed automatic closing system. The sealing gasket is the key for reliable sealing performance and it’s placed in the body. The disc is attached to the eccentric (simple or double) shaft bearing assuring an uniform seat and avoiding critical leaking by pressure discontinuities at the sealing area. In this way the sealing system assures perfect sealing under the most demanding conditions. Full bore and hydrodynamic internal design provides outstanding hydrodynamic features minimizing the head loss. The over-speed detector guarantees an appropriate closing due to over-speed of the fluid. At the same time the closing system is simple and robust offering the maximum safety.

ANGODOS AG-NZZ is an total flow non return valve, built by a cast body that allows to safely control the unique direction of a fluid within the pipe due to the closing of the shutter when slowing the fluid speed.

The closure is vulcanized to the obturator, obtaining a smooth surface with very low roughness and hydrodynamic shape, achieving a tight seal by the axial is placement of the obturator in the same direction of the axis of the pipe The shutter guide system reduces vibrations in the system even at low speeds, geting long life of the valve, reducing maintenance operations, The internal hydrodynamic design, ensures low head loss avoiding the risk of cavitation even at high speeds and  liminating the possibilities of internal turbulence. The flow is laminarized avoiding the implosion of cavitation bubbles in the walls of the valve or the pipe.

The precision in machining guarantees us the uniformity of the seat, ensuring the water tightness under the most adverse conditions. The internal hydrodynamic design and the total section, give it exceptional hydrodynamic characteristics, minimizing the loss of load,
