https://www.industryvalves.com/ Flanged Gate Valves
Flanged gate valves, also known as flanged sluice valves, are mainly used for permitting or preventing the flow of liquids in pipelines. KERUI’s valves have passed API 6D / CE certification. And those API 6D gate valves are widely applied in the fields of tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system, etc.
1. Small flowing resistance. Because fluids in flanged gate valves are often flowing in a straight-line direction.
2. Easy to open and close, and convenient to install.
3. Very low frequency of water hammer phenomenon.
4. Higher in price than check valves. Because flanged sluice valves have a lot of parts, and sealing surfaces are complicated to process.
5. Small opening torque.
6. High corrosion resistance.
7. Smooth and fine in appearance.
1. Hand wheel, handle, and transmission structure of flanged gate valves cannot be lifted.
2. Dual gate valves should be installed vertically, that’s to say, the stem is in vertical direction and handle wheel is at the top.
3. If by-pass valve is combined with flanged sluice valves, the by-pass valve should be open first to balance the entrance and exit’s pressure.
4. If those API 6D gate valves are used frequently, please lubricate them at least once per month.
1. Before installing flanged gate valves, please check valve body, sealing surface and other parts to avoid any dirt attachment.
2. Bolts at any connection joint should be fastened.
3. Inspect the packing part to ensure excellent sealing performance and ensure sluice valves to open flexibly.
4. When installing, some space should be left for flanged sluice valves to actuate.
5. The connection of actuating devices should be strictly conformed to circuit diagram.
6. API 6D gate valves should be maintained regularly.
7. Avoid collision or extrusion.

This instructional video will show you how to install or replace a shower pump.
For the purposes of this video we are installing a Grundfos Niagra 1.5 bar
shower pump. But this video will work for Salamander, Grundfos Amazon, Grundfos nile and Stuart turner. The 1.5 bar relates to the pressure output delivered by the pump.
When you receive a pump they often come with flexible hoses supplied. This makes the
installation much easier. These are rubber washers to use in water connection.
They’re very important so don’t lose them. If we look closely we can see the
water supply inlet and the rubber feet. These disperse
any vibration caused by the pump in operation. On the outlet of the pump there are two
pressure sensors. When the
pressure drops due to a shower being opened the sensors activate the pump.
Before doing any work on a shower pump ensure it is electrically isolated by switching it
off and pulling the fuse. Remove the electrical box cover and remove the wires
once you have ensured they are not live by using a volt meter.
Turn off the hot and cold water supply to the pump.
Remove the pump water connections, making a note of which ones are the inlet and
Sometimes water is still in the pipes so have a bucket or towel handy to catch any drips.
Remove the old pump.
Fortunately the new pump is the same model so no major alteration in
pipework is required.
Use the rubber washer supplied to make a watertight seal. Ensure the washer with the gauze filter
is on the inlet. This protects the pump from any debris in the water. Tighten all joints right up and turn on the water supply. Check for leaks.
Now remove the electrical cover of the new pump. Thread your wire through the nut, rubber washer and cover before connecting the wires. Identify which wires go in which terminal and using a small slotted screwdriver tighten them in place.
Now replace your electrical cover.
It’s often a good time to try and purge your system of air before running the pump. Do this by opening your shower valve.Turn on the electrics and test pump operation by using the shower.
