A valve seat installation tool is disclosed. The valve seat installation tool includes a force conversion shaft extending from a shaft front surface to a shaft rear surface along a central axis, a torque nut secured to the force conversion shaft adjacent to the shaft front surface, a head adjacent to the shaft rear surface and a pump adapter secured to the force conversion shaft between the torque nut and the head.

A Schrader valve core tool includes a driver rod extending from a handle at a first end thereof and a tip at a second end of the driver rod, the second end opposite the first end. The tip includes a fork configured to connect with a Schrader valve core connecting tip for removal or installation through a rotational motion of a threaded valve core. The fork includes a stepdown having at least one stop thereby providing alignment of the Schrader valve core tool and the threaded valve core.

Disclosed is a special-purpose valve core removal tool, including a tool body and a hexagon wrench with a tapered extractor. The tool body is detachably connected to the hexagon wrench and includes square opening portions, hexagon portions, and a clamping portion. Multiple square opening portions and hexagon portions of different specifications are arranged axially along the tool body. An internal hexagon through hole is formed in the middle section of the tool body. The internal hexagon through hole radially penetrates through the tool body. The clamping portion is radially arranged in the tool body and transversely moves along the internal hexagon through hole. The hexagon wrench is extendable to the internal hexagon through hole to be clamped with the clamping portion. Through the above structure, the problem that in a disassembling and assembling process, it is needed to replace tool heads with different sizes many times is solved.

The invention relates to a device (D) for supporting and holding the gate of a valve during a maintenance operation. It comprises two identical tools (8), each comprising a plate (80) in the form of a half-disc delimited by a generally rectilinear edge (800) and a semi-circular edge (801), the upper surface (802) of which plate (80) has a first radius, while the lower surface thereof, parallel to the upper surface (802), has a second radius which is smaller than the first radius, thereby forming a semi-circular peripheral shoulder (804), a through-cut (81) being made in the thickness of the plate (80), which through-cut, seen from above, is inscribed in a rectangle and opens onto the generally rectilinear edge (800), the side wall (810) of this cut (81) which extends parallel to the generally rectilinear edge (800) being inclined and forming an acute angle with a line perpendicular to the upper surface (802).

A valve assembly tool is provided including a beam having a shelf portion protruding from a central portion of the beam, and first and second handles extending from opposing ends of the beam. In an embodiment, the shelf portion includes a central hole defined therethrough and the tool stud extends through the central hole. In an embodiment, the tool stud includes an elongate threaded member having a locking nut at one end thereof.
