Yes. If the project is tied to a specific assembly, we can process not only standard shut-off valves but also more precise nomenclature based on a drawing or sample. This is convenient when specific seating, pressure, and connection type are crucial, rather than just overall dimensions.
Yes, such projects occur regularly. If the system requires a flanged shut-off valve, the connection dimensions, working medium, and requirements for the casing after machining are immediately factored into the calculation.
Yes. In such cases, not only the valve itself but also the shut-off valve flange is often calculated as a separate item, especially if the customer needs to restore a specific element without replacing the entire assembly.
Yes. For a number of tasks, a steel valve is more appropriate, particularly if the assembly operates under elevated load, temperature, or in an environment where a different material safety margin is required.
Yes, this is a standard format. If the project includes not only a casing part but also a steel flange or several identical connection items, it is more convenient to calculate them together with the main assembly.
Yes. If the project requires a water pump casing, it can be put into production based on a drawing, sample, or technical description. This is advantageous when the original equipment manufacturer is unavailable or lead times are excessively long.
Yes. A turbine casing can also be put into production if the project requires precise geometry, material stability, and alignment with specific equipment.
Yes. If necessary, a cast pump impeller can also be calculated, provided the customer requires not just the shell of the assembly, but its operational core with specified geometry and a defined service life.
Cast Pump Casings, Valves, and Components for Power Engineering Equipment
In power engineering, what matters is not simply a casting of the required size, but a component that operates reliably under specific pressure, temperature, and within a given medium. If the material is selected incorrectly, problems arise not on paper, but on-site: the casing warps, the flanged joint loses hermeticity, and the assembly undergoes unplanned maintenance. Therefore, the Western Foundry Group, which includes Promlit Plant LLC and Gorstal Plant LLC, accepts orders for casing parts, valves, and pipeline system assemblies based on drawings, samples, and technical specifications.
Valves and Shut-off Assemblies
One of the most frequent requests in this category is for a shut-off valve. For such parts, not only the flow cross-section and connection type are important, but also the stable geometry of the casing, leak tightness, and the behavior of the metal under operating loads. If the assembly operates in a demanding environment, the part is calculated not by its “name”, but based on pressure, temperature, and actual operating conditions.
The second major category is the 3-way valve and assemblies where it is crucial not just to shut off the flow, but to distribute it correctly within the system. Here, seating areas, mating precision, and how the casing behaves after machining and assembly are critical.
A safety valve is of equal importance. For power and engineering systems, this is not a decorative item but a functional safety element; therefore, requirements for the pressure rating, type of medium, and machining quality of primary surfaces are incorporated from the outset.
Pump Casings and Components for the Working Medium
A separate specialization is the pump casing. Such parts are ordered for water, circulation, centrifugal, and other pumps, where the material is selected according to the working medium, pressure, and the service life of the assembly. Certain alloys are more suitable for neutral media, while others are required for corrosive ones, and an error in selection is particularly costly here.
If the project involves domestic water supply or distribution networks, a water pipe shut-off valve is frequently included in the calculation. For such items, connection dimensions, casing hermeticity, and batch-to-batch repeatability are especially important. This is not a case where one can rely solely on the external contour of the part.
Special Items for Engineering Systems
Production lines and automated assemblies regularly require pneumatic valves. In such projects, the focus shifts not only to the foundry casting part but also to the precision of mating zones, because the casing must function properly as part of the finished assembly, rather than merely looking correct after knockout.
A separate category is the hydraulic shut-off valve, if the assembly operates in a pressurized system with heightened requirements for casing reliability. Here, the stability of the metal, correct machining, and the absence of deviations on datum surfaces are especially critical.
For networks where the assembly is associated with air supply, a compressed air shut-off valve is also in demand. In this product range, not only dimensions are important, but also the operating mode: pressure, open/close cycle, as well as density and durability requirements.
What is Most Frequently Sent to Production
Orders from this page typically include:
- Cast pump casings;
- Shut-off and control valves;
- Various types of valves;
- Flanges and transition elements (reducers);
- Compressor casings and related assemblies;
- Components for turbine and thermal systems.
To simplify selection from the nomenclature, the main items can be summarized as follows:

How the Order Process Works
To expedite the calculation phase, it is usually sufficient to provide:
- A drawing;
- A sample;
- A 3D model;
- A specification;
- A bill of materials for the facility.
Following this, the material, scope of work, and manufacturing lead times are coordinated. This format is highly convenient for the customer: there is no need to separately source a foundry, a machining shop, and a casing supplier for the same project.
