The design provides a tight seal and a quick reaction to the close. Forged steel globe valves, for their design, can be used with fluids that contain particles in suspension.

A globe valve is not recommended when a continuous flow is needed due to pressure drop caused by its design. Besides, they can be used in reduced spaces. This type of valve must be installed in a specific position given that the flow enters through the inferior part and comes out through the superior part. Rod packaging that allows an optimal control of fugitive emissions into the atmosphere.

The body-cover union has an adequate design to apply an even load in the gasket so that it can offer a leak-proof seal. This union is secured by a nut designed to prevent vibration and impact when closing. The spring allows these valves to function in vertical lines. It is also used when the CV needs to be increased. Rod-Gate ensemble designed for it to fail catalogo de valvulas walworth of the container catalogo de valvulas walworth in case the catalogo de valvulas walworth clogs.

Forged Steel

Piston-type check valves are generally used to walwoorth pumps or similar equipment whilst allowing the passage of flow in only one direction and preventing the return of catalogo de valvulas walworth due to backpressure. The seal in Y-pattern piston check valves provides a strong seal and a quick reaction to the close impulse. Because of their design, they are recommended when a continuous flow with a minimum pressure drop is needed.

Swing check valves are designed to produce a low pressure drop on the line. The fork and the disc allow an independent movement which achieves a correct close between the disc and the seat.

Ball check valves can be used with high viscosity fluids. Piston-type check valves can be used catalogo de valvulas walworth high viscosity fluids.

Essential factors such as reduced diametral clearance gap, controlled straightness and fine finish in the rod increase their seal capacity. Completely guided ball to ensure a catalogo de valvulas walworth seal. The stellite seat provides resistance to abrasion and erosion of the surface of the seal.

This type of valves must be installed in a specific position given its design and oriented operation features.

Dual Plate Wafer check valve. They are also used when the CV needs to be increased. Forged steel globe valves can be used with fluids that contain particles in suspension. Metal-metal seal valves can be not as efficient when the fluid has particles in suspension. The stellite coating in the seat increases wear resistance caused by abrasion and erosion in the surfaces of the seal during the flow of fluid with solids in suspension.

Ball check valves are generally used to protect pumps or catalogo de valvulas walworth equipment whilst allowing the passage of flow in only one direction and preventing the return of it due to backpressure. Posterior seal surface Backseat allows to change the rod package when the valve is completely open, and the interior is pressurized. Swing check valves are generally used to protect pumps or similar catalogo de valvulas walworth whilst allowing the passage of flow in only one direction and catalogo de valvulas walworth the return of it due to backpressure.

The stellite coating in the seat increases wear resistance caused by abrasion and erosion in the surfaces of the seal during the flow of fluids with solids in suspension. For this reason, globe valves have an arrow that indicates the direction in which they must be installed.

Y-pattern ball check valves are generally used to protect pumps or similar equipment walwotrh allowing the passage of flow in only one direction and preventing the return of it due to backpressure. Under normal operating conditions, it must be used totally open or closed. For their design, catalogo de valvulas walworth type of valves can be used in any position.
