Application of valves MZV

The main purpose is to open and close the movement of water flow in pipelines. Gate valve МЗВ and other valves with rubber wedge are used for aboveground installation on pipelines of water supply systems with pressure up to 1.6 MPa and temperature up to +75 ° C.

MZV valves are installed on the pipeline using a flange connection. This method of installation makes it possible to install flanged fittings both on a horizontal pipeline, and on a vertical one.

Wedge gate valve MVZ with a rubber wedge belongs to high-strength shut-off valves. The production of such parts is regulated in accordance with GOST.

Design features

Wedge gate valve МЗВ and similar ones are produced with a non-rising stem and a rubber wedge, the type of connection to the pipeline is flanged. The body parts and wedge are made of ductile iron, and the seals use a special high quality rubber compound. The wedge in the MZV gate valve is covered with rubber, due to this, the possibility that the gate will jam as a result of a sharp temperature change is excluded to the maximum extent. Wedge gate valve is a guarantee of complete shut-off of the flow of the working medium. The stem in the valve is double sealed. To increase the corrosion resistance of the internal parts of the valve, and to significantly increase the service life of the MZV, its constituent elements are additionally coated with a protective epoxy paint. The stem is made of corrosion-resistant steel, the cage nut is made of bronze. The seal tightness class is A (no visible leaks are allowed).

Flanged valve MVZ with a rubber wedge from the Moscow plant "Vodopribor" is a guarantee of reliability and quality

To consult on technical or financial issues, contact us by phone in Moscow (495) 726-57-37, 772-50-50, 726-57-03. Our experts will always help you with the selection of the necessary pipeline fittings and advise on the technical characteristics of the products.

Reasons to buy an MZV gate valve:

  • high reliability
  • low torque
  • sealless stem seal
  • Leakage class A - no leaks allowed!
  • Gate valves are coated with epoxy paint, which increases the corrosion resistance of materials
  • There is no risk of the valve blocking due to temperature fluctuations
  • Double spindle seal
  • There is no pit in the valve body
  • There is no stuffing box
  • Installation is carried out in a vertical and horizontal pipeline

The sales experience of the AVATEK company shows that the MZV gate valve as well as their analogues are more and more popular products. Due to the use of a rubberized wedge, the valve has improved operational parameters.

On the basis of the MZV gate valve, several modifications of locking devices are produced: MZVP, MZVG, MZVPR, ZVK. These varieties are intended for installation on pipelines used for various purposes (drinking water supply systems, fire extinguishing, etc.). Product variants differ in some design changes.

A gate valve with a rubber wedge of the type МЗВ differs in:

  • long service life without replacement of component parts;
  • high degree of reliability (mean time between failures - up to 1500 cycles).
