DIN Gate Valve

DIN Gate Valve with Brass seat
Gate valves normally have flanged ends which are drilled according to pipeline compatible flange dimensional standards. Gate valves are typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels.Gate valves are characterised as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated.

Ductile Iron Gate Valve ANSI/DIN/JIS Standard

F4 Ductile Iron Gate Valve

Gate valves are characterised as having either a rising or a nonrising stem. rising stems offer a visual indication of valve function due to the fact the stem is connected to the gate such that the gate and stem upward push and lower together because the valve is operated. nonrising stem valves may additionally have a pointer threaded onto the upper end of the stem to suggest valve role, since the gate travels up or down the stem on the threads with out elevating or reducing the stem.

WRAS rubber Gate Valve DIN PN16
Gate valves are characterised as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated. Nonrising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position, since the gate travels up or down the stem on the threads without raising or lowering the stem.

Gate Valve

The Advantages Of Gate Valve
Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.Advantages of the gate valve.1. low fluid resistanceBecause the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.2.
Gate Valves

Matters Needing Attention in the Use of Gate Valves
1. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is forbidden. 2. The double gate valve should be installed vertically (i.e. the valve stem is in the vertical position and the handwheel is at the top). 3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force). 4. Gate valve with transmission mechanism shall be installed according to the product instruction manual. 5.
Butterfly Valve

Advantages and Disadvantages of Butterfly Valve
Advantage 1. The opening and closing is convenient, quick, labor-saving, low in fluid resistance, and can be operated frequently.2. Simple structure, small overall size, short structural length, small volume and light weight, which is suitable for large-diameter valves.3. Mud can be transported, and the liquid accumulated at the pipe mouth is the least.4. Under low pressure, good sealing can be achieved.5. Good adjustment performance. 6. When fully opened, the effective circulation area of the valve seat channel is large, and the fluid resistance is small.7.
Difference Between Butterfly Valve and Gate Valve

Difference Between Butterfly Valve and Gate Valve
Different principlesButterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. It can also be used for on-off control of low-pressure pipeline media, and it mainly plays the role of cutting off and throttling. When the butterfly valve is fully opened to fully closed, it is usually less than 90. The butterfly valve and the butterfly rod have no self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the valve stem.
Butterfly Valve

The Difference Between Ball Valve and Butterfly Valve
1. Butterfly valve is composed of valve body, valve seat, valve plate and valve stem, and all fittings are exposed and can be seen at a glance; Ball valve is composed of valve body, valve core (a round ball) and valve stem. The position of valve core is inside the valve body, and only part of it can be seen by naked eyes, so the sealing performance of ball valve is better than that of butterfly valve.2. Butterfly valves are relatively simple in structure, and butterfly valves with low pressure are generally used. The zui high pressure of butterfly valves can only reach 64kg.
Pressure Test Method Of Check Valve

Pressure Test Method Of Check Valve
Check valve is a valve that relies on the medium itself to flow and automatically open and close the valve flap, used to prevent the backflow of the medium, also known as check valve, check valve, backflow valve, and back pressure valve.
Features of electric ball valve

Features of electric ball valve
The high-pressure pneumatic ball valve only needs to use the pneumatic actuator to rotate the air source by 90 degrees and a small rolling torque to be tightly closed. Completely equal valve body cavity provides medium with low resistance and straight-through flow path. It is generally believed that the ball valve is suitable for direct opening and closing applications, but recent developments have designed the ball valve so that it can be used for throttling and control systems.
The development trend of electric butterfly valve

The development trend of electric butterfly valve
Electric butterfly valve means that the butterfly valve is equipped with an electric actuator, which controls the opening and closing of the valve through the electric energy provided by the power supply, so as to realize remote centralized control and automatic operation. Electric butterfly valve can be divided into flange type and disc type according to the connection method, which is an important execution unit in the field of industrial automation control.
Check Valve

Common Check Valve Materials
Check valve is a valve installed in the pipeline to prevent the backflow of media. Check valves can be used on many types of pipelines such as over water, oil and gas, etc.

What Is The Advantage for Butterfly Valve
Butterfly Valve is a simple structure control valve,it can be used for switching control of low pressure pipeline medium. Our Butterfly Valve is a kind of valve that the disc rotate around the valve shafts to open and close. Features:1, opening and closing convenient and rapid, labor saving, fluid resistance is small, can often operate.2, simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve.3, can transport mud, the least liquid in the pipe mouth.4.
