A three-way ball coupling valve with a lock (see Fig.1) consists of a housing 1 and fittings 2.
The fluoroplastic saddles 3 are pressed against the plug 4 when tightening the fittings.
The connections of the housing with the fittings are sealed with gaskets 5. The spindle 6 is sealed with a set of fluoroplastic rings 7 and
a ring 8. The compression of the rings 7 is performed by a nut 9. The crane is switched manually by turning the handle 10, which is fixed on the spindle with a nut 11. The lock 12 is designed to lock the handle from turning in various working

Supply of the working medium – according to the scheme (see Fig.2.)
In position 1, pressure measurement is carried out,
in position 2, pressure relief from the pressure gauge,
in position 3 – purge.
It is possible to connect a control pressure gauge to the middle branch pipe through
The control is carried out in position 4.

The three-way valve for the pressure gauge is designed for connecting, checking and purging control and measuring devices. It is installed on boilers, pipelines, vessels, tanks and equipment operating under pressure. It can be used as a shut-off and distribution valve for merging and separating flows. Working environment – hot and cold water; wet and superheated steam, light oil products, natural gas, air and other substances with weak chemical activity.
The crane is assembled in a 12X18N10TL stainless steel housing. It has:
When the pressure of the transported medium is up to 0.6 MPa, the fitting connection of the three-way valve for the pressure gauge can be replaced by a conventional coupling.
Structurally, the three-way crane has 4 working positions:
The control is carried out by moving the rotary knob in one of these directions. When installed on steam pipelines, purging must be performed every shift.
The price of three-way valves for a pressure gauge varies depending on many factors, including the design of pressure, diameter and material. Additionally, the individual wishes of the customer are taken into account.
You can buy a three-way crane at a low cost 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 firstname.lastname@example.org
Delivery of cranes for the pressure gauge is carried out by the services of transport companies – Business Lines, PEC. Also, transportation is carried out by rail Zheldorexpedition and other types of delivery with payment for transport services and cargo insurance services by the buyer.
