For example, a standard gate valve has three holes the upstream port, where material flows into the body; the downstream port, where material leaves the body, and another hole on top to connect the bonnet and actuator. Of course, many valves have three or more ports as well, but the basic configuration is similar. discshaped valve member

In order to facilitate the formation of a plastic member with an aperture in a central portion thereof, a ring gating valve arrangement is provided with a multipiston servo arrangement which enables a specially configured pin to be stepwisely reciprocated back and forth within a molding device. The pin is formed with a land at one end which is dimensioned and shaped to produce the required
A knife gate valve (10) comprises an elongated, relativelyflat rigid frame (16) having two rigid side plates (24 and 26) being spaced from one another. A relativelyresilient valve liner (14), forming a valve seat about a liquid flow passage (22) through the frame (16) is insertable into the frame (16) from a first end of the frame so that the liner (14) can be replaced without detaching the
debris. In general, the AWWA operating formula for opening/closing a gate valve is 3 times the nominal valve size plus 2 or 3 turns of the operating nut. (Example; 6 x 3 = 18 plus 2 or 3 = 20 to 21). However, each valve manufacturer has detailed operation and maintenance procedures for each of the various types of valves1. Valve Diameter (in)
Valve diameters 2 inch 4 inch For lockout in the closed position, place the pin through the lower hole in both the yoke legs and the hole in the gate. For lockout in the open position, place the pin through the upper hole in both the yoke legs and the hole in the gate. Valve diameters 6 inch 24 inch For lockout in the closed position
There are quite a few different types of connections used to install valves and other process components in piping of process systems. While they all perform the same function of connecting the valve into the piping system and allowing it to perform its function, each connection type has its own pros and cons.

The seat rings are steel and makeup part of the valve trim. They are pressed into the valve body and wedged into place, forming a seal with the body. The seating surfaces are ground and lapped. 7. WEDGE. The wedge, which is solid design, is forged or investment cast steel and is part of the valve trim. The seating surfaces are ground and lapped.
Gate valves will last longer if they are only used infrequently. For applications where the flow of fluids needs to be turned on and off regularly, a ball valve is a much stronger choice. Advantages of gate valves Low resistance The design of a gate valve is simple, allowing water to pass straight through.
line, ERU Knife Gate Valves K1 are clamped between two flanges of the pipeline and fastened with bolts from flange to flange as well as with bolts in the tapped blind holes of the body. In order to avoid distortion of the Knife Gate Valve, the counterflanges must be in true alignment with one another and all bolts have to be tightened evenly.
A gate valve is the most common type of inline valve used for opening and closing the flow of water in a water main. Gate Valves come in many different sizes depending on the watermain they are being attached to. The primary purpose of a mainline gate valve is for shutting off or isolating certain

Knife gate valves like the ERHARD ERU K1 are among the mostused valves, not only in the wastewater sector. They are also used to regulate other liquids as well as solid and gaseous media. An important advantage of the knife gate valve design is the fully free passage when the valve is open. The pressure losses are therefore very low.
