Valve system, piping manifold and pump system

A piping manifold comprising:

• a pipe;
• and
• a valve system comprising at least two valves, wherein a pipe section of each valve forms an integral part of the pipe, each of the at least two valves comprising:
• the pipe section of the pipe, wherein the pipe section defines a primary flow direction;
• a valve opening in the pipe section;
• a valve seat;
• a valve body, wherein the valve opening, the valve seat and the valve body define a common valve axis extending transversely to the primary flow direction;
• an operating element arranged at the pipe section diametrically opposite from the valve opening, wherein:
• the operating element is configured to control the valve body for selectively operating in a check-valve mode, in which the valve body is movable along the valve axis to open the valve opening upon a fluid flow from the valve opening towards the valve body;
• and
• the operating element is configured to control the valve body for selectively operating in a shut off-valve mode, in which the valve body is fixed against the valve seat to close the valve opening for any fluid flow direction.

A pump system comprising:

• at least two pump assemblies;
• a common outlet pipe, wherein the at least two pump assemblies are fluidly connected in parallel to each other to the common outlet pipe;
• and
• a valve system comprising at least one valve for each pump assembly, wherein a pipe section of each at least one valve for each pump assembly forms a part of the common outlet pipe, wherein each at least one valve for each pump assembly comprises:
• the pipe section of the common outlet pipe, wherein the pipe section defines a primary flow direction;
• a valve opening in the pipe section;
• a valve seat;
• a valve body, wherein the valve opening, the valve seat and the valve body define a common valve axis extending transversely to the primary flow direction;
• an operating element arranged at the pipe section diametrically opposite from the valve opening, wherein:
• the operating element is configured to control the valve body for selectively operating in a check-valve mode, in which the valve body is movable along the valve axis to open the valve opening upon a fluid flow from the valve opening towards the valve body;
• and
• the operating element is configured to control the valve body for selectively operating in a shut off-valve mode, in which the valve body is fixed against the valve seat to close the valve opening for any fluid flow direction.
