Custom-built for every stage
of your installation.
01 / 15
Differential Pressure Valve
Differential pressure control valves sense the pressure difference between the inlet and outlet of a line to maintain a stable differential pressure across the system, automatically balancing flow fluctuations for efficient, stable operation.
02 / 15
Strainers
Strainers separate solid particles, sediment and foreign matter from the system; the fluid is filtered as it passes through the strainer body, protecting valves, pumps and heat exchangers.
03 / 15
Thermostatic Valves
Thermostatic valves automatically control the hot-water flow into a radiator based on room temperature, keeping the room temperature stable, preventing unnecessary energy use and contributing to hydraulic balance.
04 / 15
Fittings
The Cerkar fittings family — check valves, nipples, nuts, tees, elbows, unions, meter unions and plug groups, all under one roof.
05 / 15
Fittings · Check Valve
A check valve allows fluid to flow in one direction only and automatically prevents reverse flow, reducing back-flow, water hammer and equipment damage on pump shut-downs.
06 / 15
Fittings · Nipple & Reducer
A nipple connects two pieces of equipment or fittings, usually threaded at both ends. Reducers provide a secure, leak-tight transition between lines of different diameters.
07 / 15
Fittings · Nut Group
Nuts mechanically join two parts and fix the connection with clamping force, widely used in flange connections, mounting feet and general mechanical assembly.
08 / 15
Fittings · Tee Group
Tee fittings distribute the fluid in a line into two directions or merge two lines into one, directing flow in a controlled, leak-tight way.
09 / 15
Fittings · Special Tee
Tee fittings produced in special size and connection combinations — movable / male / female thread variations to suit the project.
10 / 15
Fittings · Elbow Group
Elbow fittings change the direction of flow in a pipe line by a specific angle (usually 90° or 45°), shaping the route of the installation.
11 / 15
Fittings · Unions & Extensions
Brass unions provide a secure, leak-tight and detachable connection of pipes and equipment in liquid and gas lines. Extensions increase the threaded connection distance and align the line.
12 / 15
Fittings · Meter Union
A meter union connects water, gas or heat meters to the pipe line in a secure, leak-tight and detachable way, with a gasket and a nut-clamping mechanism.
13 / 15
Fittings · Plug Group
Plugs close connection points on lines or equipment bodies and ensure leak-tightness, safely capping unused outlets or maintenance ports.
14 / 15
Thermowell Group
A thermowell lets temperature measuring elements (thermometers, sensors, etc.) be mounted safely into the process line, protecting the element from the pressure, temperature and mechanical effects of the fluid.

Other plumbing products such as safety valves, fill valves, zone valves and radiator valves.
