2-Way Ball Valve: Fire Safe Type: F100 Series

Manually Operated Valve F100 Model	Pneumatically Operated ON-OFF Valve ( Double Acting) FPN1100 Model	Pneumatically Operated ON-OFF Valve (Single Acting) FPO1100 Model	Electrically Operated Valve FMSJ4100 Model

Feature

1) NDV's general-purpose standard ball valve.
2) Fire Safe type: In the case sealing parts such as the seats or packings are destroyed by a fire etc., it can prevent considerable leakage of fluids.
3) Stem Guard Mechanism: Can prevent stems from blowing out due to excessive fluid pressure.
4) Antistatic Mechanism: Can prevent the build up of static electricity within the valve due to the friction between the ball and seat.
5) The standard seat is made of NEW PTFE. Other seats are made from various enhanced materials or have reinforced inner/outer bores. NDV has a selection of seat materials to meet your requirements.
6) Choose an actuator that meets your requirements. Applies to manually operated, pneumatically operated, flow controlling, and electrically operated types.

usage
Chemical, environment/water treatment, iron and steel, ship, semiconductor, food, power industry and other secotor

2-Way Ball Valve: For Special Purpose

Jacketed Ball Valve E100J Model	Extended Gland Type FEX100 Model

Feature

1) Jacketed ball valves are valves built with a jacket that forms a second layer covering the body. The purpose of this jacket is to supply hot water or steam through it to heat up the fluid in the valve body (also used for cooling purposes). Applies mainly to fluids that coagulate at room temperature.
2) The extended gland type mainly applies to cases where insulation material is attached to the piping. Because the stem is extended, it is easy to work with and to tighten up the gland packing.
3) Choose an actuator that meets your requirements. Applies to manually operated, pneumatically operated, and electrically operated types.

V-Port Valve: V100 Series

Manually Operated Valve V100 Model	Pneumatically Operated ON-OFF Valve (Double Acting) VPN1100 Model	Pneumatically Operated Control Valve VPN3100 Model	Electrically Operated Valve VMSJ4100 Model

Feature

1) The V-shaped cut opening of the hemispherical ball makes smooth operation by cutting fibers and solid bodies and also excellent fluid control capabilities.
2) This valve has seat at only inlet side to minimize the jamming of solids.
3) Choose an actuator that meets your requirements. Applies to manually operated, pneumatically operated, flow controlling, and electrically operated types.

usage
Paper mill factories (pulp fluids etc.), slurries (iron oxide, muddy water, lime milk etc.), powders (fly ash and resin pellets such as nylon ), and highly viscous fluid lines.

3-Way Ball Valve: E300 Series

Manually Operated Valve E300 Model	Pneumatically Operated ON-OFF Valve (Double Acting) EPN1300 Model	Pneumatically Operated ON-OFF Valve (Double Acting) EPN1300 Model	Electrically Operated Valve EMSJ4300 Model

Feature

1) The Valve has 3 dirction flow path, used for switchover, distribution, and mixing. It has cost merit and space saving compared with using many 2-way ball valves.
2) The L-port type, for the switchover of fluids, and the T-port type, for switching distribution and mixing of fluids are also available.
3) Choose an actuator that meets your requirements. Applies to manually operated, pneumatically operated, and electrically operated types.


usage
Chemical, environment/water treatment, iron and steel, ship, semiconductor, food, power industry, and other sectors.

Y-Shaped 3-Way Ball Valve: Y300 Series

Manually Operated Valve Y300 Model	Pneumatically Operated ON-OFF Valve (Double acting) YWN1300 Model

Feature

1) Compared with the 90 degree angle of general 3-way ball valves, the Y-shaped 3-way ball valve has a wide angle of 135 degrees. It is useable for fluid of low fluidity such as powers or slurries, pipe cleaning pigs, and passing spheres.
2) There are two types of flanges, the straight type or curved type with a 22.5 degree. Combine these two flanges at the three ports for any one of a possible 54 piping patterns for best solution for your purpose.
3) Choose an actuator that meets your requirements. Applies to manually operated, pneumatically operated, and electrically operated types.

usage
For solid material such as Powders, slurries, pellets or for shield machine use.

Large Bore, High Pressure Valve, and Other Special Purpose Ball Valves

For High Pressure EG100S Model	2-Staged Open/Close Type FPN3100 Model	For Shield Machine EKTON1100 Model	Top Entry Type T100 Model

Feature

NDV takes orders for large bore or high pressure ball valves. We also extensively offer step operation which allows certain amounts of fluids to pass in a 2 staged open/close type, hydraulically operated valves for shield machine, and top entry types developed for nuclear power plants.
