Three-piece ball valves

Simple construction and operation, a small installation space compared to the other valves, fast opening and closing by rotating the handle in 90°, a circular cross section with a full or narrow passage, a very small hydraulic resistance because there is no turning of flow line of the fluid, baukasten principle of building - easy maintenance and reduced cost of stocking spare parts, various material combinations offer the possibility of wide area of application.

Two-piece ball valves

Two-piece ball valves with thread fit for nominal pressure PN 16, 25, 40 and 63, and at the request of the customer we produce PN 100 i 160 as well as Class 150, 300, 600, 800, 900, 1500. Operating temperature is limited by applying teflon (PTFE) as a sealing material up to max. 200°C. The area of application is very broad, so it includes their application and installation in the lines with non-aggressive and aggressive fluids in consultation with the manufacturer.

Two-piece ball valvesTechnical characteristics

Technical solution

Basically technical solution is very simple, based on a "anty blow" system, that is there is no possibility for spindle to fell out from valve due to working conditions or failures. Mounting the spindle goes from inside the case.

Materials

Two-piece ball valves with thread are by default made of carbon steel W.Nr.1.0619, W.Nr.1.1151, and stainless steel W.Nr.1.4581, W.Nr.1.4571, W.Nr.1.4552, W.Nw.1.4541, W.Nr.1.4408, W.Nr.1.4301. Other matherials are possible if asked.

Gaskets for standard solution are made of teflon (PTFE).

Gaskets on ball for PN 100 and 160 are made of teflon coated with metal.

Mounting and connection measures

Standard design for two-piece ball valves with thread is produced according to EN 10266-1, with connection measures for internal G thread Type: DLS-NG.Č or DLS-NG.K.
By customer request, we are able to do construction with measures:

  • for the metric internal thread Type: DLS-NM.Č or DLS-NM.K
  • for NPT thread according to ASME B1.20.1 – Type: DLS-NNPT.Č or DLS-NNPT.K

Operating pressure and temperature

Two-piece ball valves fit for nominal pressure PN 16, 25, 40 and 63, and at the request of the customer we produce PN 100 i 160 as well as Class 150, 300, 600, 800, 900, 1500.

Operating temperature is limited by applying teflon (PTFE) as a sealing material up to max. 200°C.
Application area in relation to pressure and temperature is shown on the P-T diagram for teflon (PTFE), and it directly depends on the possible working pressure and working temperature.

TESTING

Each valve is tested after assembly for the hydraulic pressure and sealing according to EN 12266-1.

The area of application

The area of application is very broad, so it includes their application and installation in the lines with non-aggressive and aggressive fluids in consultation with the manufacturer.
