Features

The fixed ball type has a structure in which the upper and lower portion of the ball are supported and fixed by the stem and trunnion as shown in Fig. 3. With this structure, the fluid is closed using the spring force at the back of the seat and the pressure on the primary side applied to the back of the seat when fully closed. Therefore, the seal is on the primary side, and it is characterized by less fluctuation of operating torque against fluctuation of flow pressure. It is mainly used for high pressure (JIS30K, CL600 or higher) and large bore size (DN250 or higher).

①Easy operation of fully open and closed

②Excellent sealing

③Extremely low pressure loss

④Compatible with high-temperature and high-pressure fluids

⑤Easy to automize

We also apply requests for special purpose valves used under high pressure and those for shield machine and nuclear power plants.

Fig. 1

Features

The floating ball type has a non-fixed connecting structure of the ball and stem so that the ball moves in the flow direction when fully closed as shown in Fig. 2. With this structure, a self-sealing effect can be expected by pressing the balls against the secondary seat due to the differential pressure when the valve is fully closed. It is mainly used for low pressure (up to JIS20K, CL300) and small bore size (up to DN200).

①Easy operation of fully open and closed

Fully open　Fully closed

Opening and closing operations can be performed quickly by turning the stem 90 degrees.
In addition, the open/close state of the valve is clearly indicated by the position of the lever handle, so it has excellent visibility.

②Excellent sealing

PTFE and other plastic materials are used for the valve seat, which makes it easier to stop the fluid with excellent sealing performance.

③Extremely low pressure loss

Since its flow path has the same shape as the piping and there are few elements that give resistance to the fluid, the structure has an extremely low pressure loss when fully opened.

④Compatible with high-temperature and high-pressure fluids

⑤Easy to automize

Our ball valves can be equipped with various types of actuators by simply attaching a yoke and coupling.

Since there are many types of materials for the main bodies and diaphragms, and the materials can be selected according to the composition of fluids such as rubber and fluorocarbon resin, the most suitable selection is available, when high cost performance and corrosion resistance and chemical resistance are required.
3. Actuators can be selected according to the application as well.

Manufacturer: NIPPON DAIYA VALUE Co., Ltd.

Model: Pneumatically Operated Control Valve BO3400 type

NDV’s representative product, the diaphragm valves, are superior in “air-tightness,” “maintenance,” and “corrosion and chemical resistance.”
Since it can be configured by selecting from a wide range of materials according to fluid and usage conditions, it is applicable to a wide range of fields and has excellent cost performance.
Based on our extensive experience and achievements cultivated over our long history, we provide high-quality, high-performance and reliable products.
