Due to the fact that the inner diameter of the collar flange corresponds to the inner diameter of the rotary shutter, this method of installation ensures proper clamping saddle seals (elastomer). Flat flanges, dressing during installation on the pipe, have a large hole, which prevents the correct terminal elastomer and leads to its destruction.

When you need to use the mixing valve, and when the ball valve?

Brass ball valves are recommended for heat pipes with high pressure working environment, with a diameter of 400-500 mm, requiring high containment.

Brass ball valves are useful for mounting internal wiring in the home of engineering networks, pipelines with temperatures up to 95-100 ⁰ C and pressures up to 6 bar with a diameter of 15-50 mm.

In other cases, the optimal solution is the use of backflow preventers.

Can I use backflow preventers to control water flow?

The shutter is not ideal for controlling flow of coolant. It can operate in half-open position, but has an unstable control over the entire range of opening. From an economic point of view, the use of the rotary shutter with motorized for automated control has little advantage over the saddle valve. Wilkins backflow preventer for less than the valve, but the management needs of working actuator action, which has a high frequency of operation. This drive is much more expensive than the electric line of action, which is used to control valves, and specially designed to regulate.

On the other hand, the mixing valve is advantageous to use for manual adjustment of the coolant flow rate for which it is possible to lock the handle in an intermediate position.

Can I put the backflow preventers on the heating pipes?

In the heat pipes (diameter 400-500 mm) is recommended to use Brass ball valves, which have a high integrity, and are more resistant to high temperatures. In the pipeline with a diameter over 500 mm is advantageous to use backflow preventers for heating, as they are not inferior to the parameters of ball valves, but substantially lower in price.

Can I install the mixing valve on the steam?

At the recommended set of pairs of semi shut-off valves. The dramatic opening of the backflow preventer can lead to water hammer in steam lines, and the gradual opening of the shut-off valve to help avoid it. It is not recommended to put on pairs of backflow preventers with soft seals the saddle, due to the high temperature steam (120 ⁰ C). Acceptable use of backflow preventers for steam special version (with the seal of the “metal on metal”) and the gearbox for a smooth opening of the shutter.

Why are backflow preventers should be installed horizontal axis?

In the case of vertical mounting axis of the bolt at the bottom of the bolt running stagnant zone is formed. In this area, can accumulate solids (sand, silt, iron oxide) that when you turn the rod may cause it to jam. This does not mean that the valves can not be applied in horizontal pipes – in this case, you need to install the bolt so that the axis was at an angle or horizontally. In this case, the particle flow in the lower part of the bolt will not accumulate.

Why are backflow preventers are installed only in the open position?

This rule is valid for valves with soft saddle seal. With the contraction of the elastomer is deformed flanges and a sort of “wraps” the gate drive. When trying to open a gate is destroyed elastomer. When installing the bolt in the ajar position and seal is deformed, but it does not affect the sealing backflow preventer, and closing a shutter additional sealing drive.

What is the maximum temperature of backflow preventers with soft seals saddle?

backflow preventers with soft seals saddle is not recommended to put on fluids over a temperature 90-110 ⁰ C. The high temperature consolidation and expansion of the disk can lead to the destruction of the elastomer during opening and closing the shutter. For a pair of saddle valves are recommended, and for hot water – ball valves or backflow preventers with the seal of the “metal on metal.”

What are the main advantages and disadvantages of taps, valves, valve?

Ball valves.

Advantages: small time of closing and opening, low pressure drop, low height and the length of the building.

Disadvantages: high torque necessary for driving, the need for (some varieties) of non-metallic sealing elements.

Backflow preventers.

Advantages: low hydraulic resistance, there are no areas in which particles can accumulate and dirt, the relatively small size and weight.

Disadvantages: reduced gate leakage, high torque on the shaft due to the large unloaded forces acting on the disc, the difficulty of obtaining the calculated characteristics of the crossing gate while working as a regulating valve.

Shut-off valves (valves).

Pros: the ability to work under high pressure drops in the body and shut-off for large values ​​of working pressure, ease of construction, maintenance and repair in the operating conditions, a small course of closing element needed to complete overlap of the aisle.

Disadvantages: high hydraulic resistance, inability to use the flux-polluted environments, as well as in media with high viscosity, the ability to supply fluid in one direction only, due to the construction of the valve.
