Heated ball valves (DN15-200, PN 1.6-4.0 MPa)


as Russian-made shut-off devices on technological lines of oil refining, chemical pulp and paper and other industries with liquid and gaseous, including aggressive, working media, where, according to operating conditions, heating of the working medium is necessary to avoid solidification.

Heated ball valves are intended to be fitted as stop/shutoff valves in the process lines at chemical and oil-refining plants, as well as at pulp-and-paper mills and other production facilities using fluid, gaseous as well as corrosive working media where working medium heating is required in order to avoid gelation, for instance, in the process lines of liquid sulfur or chocolate. Distinctive features of these valves are special design of ball and ball seat which provides advanced reliability, and also stamp-welded design of body and heating jackets and casting design of valves.

The valve body comprises the inner pipe and the shell, which are forming an annular chamber. Into this chamber, the heat transfer agent is admitted via the nipple to heat the working medium. The valve body and the ball (3) are sealed with the ball seats (5). The cap-body joining is sealed with the joint gaskets (7). To tighten the ball seats (5) and the joint gaskets (7) the flanges are to be bolted together by stud bolts until the ball seats stop positively against the valve body (1). The blowout proof valve stem (4) is sealed with stem packing (8) and stem seal (11). Valve shifting is performed by turning handle (12) through 90 degrees. Remotely controlled valves provided with pneumatic and electrical actuators are available. The valve can be mounted on the pipeline in any attitude position required. The valve can be supplied with the valve-locking device.

A heated ball valve is used as a shut-off device for installation on pipelines transporting heated products that can solidify or condense during cooling. As an example of such an environment, dark petroleum products, chocolate, liquid sulfur, water vapor can be called. The main feature of this valve is the presence of a steam shirt of the body and the use of heat-resistant fluoroplast F4K for seals.


General description

Structurally, the heated crane is a standard shut-off valve of an inter-flange installation, equipped with two clamping flanges and 4 tie pins. The main assembly elements are:

  • steel body with steam jacket;
  • locking hollow plug;
  • rotary rod (spindle);
  • handle, and for DN 150 and 200 mm gearbox;
  • two flange, welded or coupling nozzles;
  • sealing elements made of fluoroplast.


The case material can be stainless, carbon or frost-resistant steel. In accordance with the technical specification of the customer, the ball valve with heating can be equipped with a pneumatic or electromechanical drive. Similar products are used in automated and remote control systems.


Operational characteristics

  • the diameter of the conditional passage is from 15 to 200 mm in standard denominations;
  • working pressure up to 1.6, 2.5 and 4.0 MPa;
  • ambient temperature from -60°C to +160°C;
  • climatic version according to GOST 15150-60 UHL1 from -60°C to +50°C.

The working resource is not less than 8000 cycles. The estimated service life is 10 years.


Cost and delivery

The price of a heated ball valve varies depending on many factors, including pressure, diameter and material design. Additionally, the individual wishes of the customer are taken into account.

You can buy a ball valve at a low price in JSC “RC “Fobos” by making an application by phone 8 (800) 700-62-60 (Moscow and all Russia) or using the services of regional managers, as well as by e-mail

Delivery of cranes is carried out by the services of transport companies – Business lines, PEC. Transportation is also carried out by rail Zheldorexpedition and other types of delivery with payment for transport services and cargo insurance services by the buyer.
