Pressure and temperature regulators at the best price with delivery
Pressure and temperature control valve
We can offer you a wide range of differential pressure and temperature regulators made of brass and cast iron for water and air. Highly efficient pipe fittings ensure smooth and stable adjustment, reduce the occurrence of noise on control valves and simple balancing. On our website you can buy regulating devices of direct and indirect action from leading brands with different types of adjustment, variable sizes at the most affordable price.
The temperature and pressure regulator can be normally closed (“before itself") and normally open (“after itself"). They may differ in design features, but their task is the same — to maintain a stable pressure in the pipeline. If the pipe fittings are installed correctly, full autonomous and automatic operation in the networks is provided.
The pressure regulator “after itself” is a normally open control valve, which is designed to automatically maintain the desired pressure of the working medium by changing the flow rate before the adjustment object. It is used for liquid and gaseous pipelines: air, water, low-pressure steam, non-aggressive coolants and gases. For example, the Pressure regulator Valve-Daddy PRB "before itself" cast-iron flanged.
Its principle of operation is based on balancing the force created by the difference in the pressure parameters of the working medium and the elastic deformation force of the spring. The adjustment process is possible only if the working medium is consumed. The design includes: a housing, a sensing element made of a membrane, a spring for adjustment and a pressure sampling tube.
Technical parameters:
- housing and seal material;
- working pressure;
- bandwidth;
- maximum and minimum operating temperature range;
- special purpose;
- connection type and thread features;
- installation location.
Functions of the pressure regulator “before itself”:
It consists in reducing /increasing the flow of the working medium directly through the regulator valve, ensuring constant pressure to the installation site of the pipeline fittings. And to maintain a stable pressure difference between the two pipelines, a separate type of pressure reducing valve is provided — a differential pressure regulator.
Modern control valves are used most often in water heating systems with hydraulic mode. >The water pressure regulator allows you to achieve a stable pressure, improving the functioning of the heating network. If the installation is done correctly, the heating equipment will be completely protected from zero consumption.
The differential pressure regulator is used for:
- reduction of water consumption;
- neutralizing hydraulic noise;
- pressure stabilization;
- protection of equipment from breakdowns due to a sharp pressure drop.
Automatic temperature and pressure regulators do not require maintenance. They are able to accurately maintain the specified parameters without additional integration into the system.
The main field of application of regulators “after itself":
- water supply systems;
- individual and central heating points;
- boiler installations.
In the IHP, the differential pressure regulator is installed: on the supply/return pipeline of the heating circuit of each system individually or on the supply/return pipeline at the input of the heat network. Before ordering the pressure valve on the DN.RU website, pay attention to the following characteristics: nominal diameter, temperature limit range, connection type, maximum operating pressure, CPS, type of the serviced medium.
The service life directly depends on the features of operation and the correct installation. Here are the main recommendations for installing normally-open pipe fittings:
- Installation is possible only on a horizontal pipeline.
- The position of the regulator body must be correctly oriented.
- The length of the flat section without turning in front and behind the valve is at least 5 diameters.
- There should be a straight section of pipeline between the housing and the pressure relief tube, equal to at least 5 diameters of the nominal cross-section.
On our website Valve-Daddy a large range of differential pressure and temperature regulators made of brass and cast iron for water and air is presented. Highly efficient pipe fittings ensure smooth and stable adjustment, reduce the occurrence of noise on control valves and simple balancing. On our website you can buy regulating devices of direct and indirect action from leading brands with different types of adjustment, variable sizes at the most affordable price.
Here you will find a pressure regulator “before” and “after” with the right type of connection to the pipeline: screw, flange, welded. The online catalog also presents control valves and other pipeline fittings of domestic production of the budget and premium segment. Delivery is carried out throughout the country.
