GATE VALVES & CHECK VALVES Filter cartridge VT.157

Check valves with Valtec brass spool (VT.151) are designed to regulate the flow of carriers: they allow liquid or gas to pass in the desired direction and prevent reverse flow. This model features the presence of a spherical spool chamber, which ensures higher throughput of the valve.

The non-return valve Valtec (VT.151) with brass spool is used to equip plumbing and heating systems, as well as transport networks for conveying liquids and gases, the components of which are structural parts relative to fittings. Installing such accessories can protect the entire transportation system and the equipment and equipment connected to it, and increase operational resources to prevent accidents and decompression.

Check Valves Nickel-plated Valtec (VT.161) with a spool valve mechanism designed to regulate the current carrying: they allow the passage of liquids or gases in the desired direction and prevent reverse flow. The mechanism itself consists of the following parts in structure: the upper and lower plates plus a valve stem. Due to the materials used to make the valve core (nylon) and spring (stainless steel), these fittings are highly resistant to various influences - mechanical, chemical, thermal.

Purchase of check valves with spool mechanism in Moscow are used to equip piping and heating systems, as well as transport networks for conveying liquids and gases, the components of which are chemically inert with respect to the structural parts of the fitting. Installing such accessories can protect the entire transportation system and the equipment and equipment connected to it, and increase operational resources to prevent accidents and decompression.

The check valve Valtec (VT.171) with drain and vent is a combined version of the multifunctional accessory. This device, installed in a network or heating/water supply system, has several functions: prevents backflow of carriers, drains liquids and eliminates air pockets.

Fittings come with manual vents (for vertical mounting) and drain plugs. Install additional fittings in specially supplied sockets with ¼” threaded fastening. Where fittings are arranged horizontally, the exhaust port can be replaced by a pressure gauge.

Check valves with drainage and ventilation openings are used to equip plumbing and heating systems as well as transport networks for conveying liquids and gases, the components of which are chemically inert fittings with respect to structural components.

When installing, pay attention to the marking of the valve body, where the arrow indicates the installation direction of the flow direction.

Gravity systems are known as heating systems, where the fluid moves naturally. Such systems can often be found in private households. In some cases, flow direction and cycle acceleration determine the pump installed in the bypass. In the absence of forced force (pressure), the coolant circulates naturally. To prevent the liquid from moving in the opposite direction due to gravity, special but not spring-loaded float valves are used.

Purchase a gravity system check valve Valtec (VT.202) and install it in the gravity system in the area parallel to the bypass where the pump is installed. When the pump is running, all the coolant will be bypassed to the heating system.
