製品紹介

Our main products are marine valves, water works valves and other industrial valves. Since many of them are very common types of valves, clear explanations have often been neglected in the past.  Despite their simplicity, valves are very important to many aspects of our life.  Here, we would like to spotlight some of our product line-ups.

Marine Valves

This category of valves is used for building tankers, LNG/LPG carriers, bulk carriers, and navy ships. Such vessels are described as ‘plants’ on water; various types of valves are critically necessary. We provide a wide selection of valves in order to meet your needs.

Shipbuilding-Cast iron globe valves

Reference Standard JIS F 7305、7307、7309
Nominal Pressure 5K、10K、16K
Nominal Diameter 50~400A

This valve is one of our most commonly used products.  Because of its round shape, it is called the globe valve.  It delivers very high shutoff performance as well as a flow control capability.  We also produce a needle-type variant, which gives even more flexible flow control.

Shipbuilding-Cast iron gate valves

Reference Standard JIS F7363、7364、7369
Nominal Pressure 5K、10K、16K
Nominal Diameter 50~600A

This valve is called a gate valve because of its flow dividing structure and is used commonly for marine vessels. With its internal thread, it is useful for the limited spaces of a ship. An external screw valve requires extra space for its shaft to rise.  To shut off fluid flow, move the wedge shaped disc up and down.  Moreover, this type of valve has much less pressure loss than others do.

Shipbuilding-Cast iron hose valves

Reference Standard JIS F 7333
Nominal Pressure 5K、10K
Nominal Diameter 50A、65A

This valve, connected to a hose, is used for a firefighting operation or cleaning decks.  As for hose coupling shapes, we have Nakajima-Style, Noma-Style, ANSI, STORZ, BSS336 etc. available.

Water Works Valves

This category of valves is used mainly at water treatment facilities and night soil disposal plants.  These products are made to be strongly anti-corrosive, which is ideal for the typically used fluids such as sewage sludge or night soil. We currently provide the following valves to various water treatment centers across Japan.

Sluice valves for water works

Reference Standard JIS B 2062、2031
Nominal Pressure 7.5K、10K
Nominal Diameter 50A~600A

This outside screw gate valve is used at water treatment facilities.  The epoxy resin paint for water works with 385µm film thickness is applied to the internal surface.  For the nominal pressure of 7.5K spec version, an official inspection for Japan Water Works Association is standard at our company.  Because of this outside screw position, any foreign material in fluid never contaminates the threaded area of the valve shaft, so opening and closing operation is very smooth.  It provides high performance when it is either fully open or fully closed.

swing check valves for water works

Reference Standard JIS B 2062、2031
Nominal Pressure 7.5K、10K
Nominal Diameter 50A~600A

This swing check valve is used at water treatment facilities.  The name, swing, comes from its unique structure, in which the valve disc hangs by an arm and hinge pin so it swings.  Self-closing by its own weight or back pressure, it has less pressure loss than other types of valves.  Metal touch and rubber touch are both available for the disc surface.  We also produce counter-weight, dash pot, and bypass styles as well.

Motor operation gate valves

Reference Standard JIS B 2031、2062
Nominal Pressure 5K、7.5K、10K
Nominal Diameter 50A~600A

This gate valve opens and closes with motor operation generated from the actuator and gears inside.  This is one of our top products; we produce 150 units in total annually, mainly for water and various industrial plants.  For other motor operated types, ball and angle valves are also available.

Gray cast iron gate valves

Reference Standard JIS B 2031
Nominal Pressure 5K、10K
Nominal Diameter 50A~1000A

This outside screw gate valve is for industrial use.  Specifications with diameter ranged from 50A to 1000A are available.  It has strong resistance to different kinds of fluids because of its ductile cast iron body material.

Gate valves for air

Reference Standard JIS B 2031
Nominal Pressure 5K、10K
Nominal Diameter 50A~600A

This gate valve is used for air, as compressive fluid. The material for the valve seat is CAC406, so this material shuts off gases or fluids very well.  To increase more resistance to high fluid temperatures, silicon heat-resistance coating is applied to the inner and outer surfaces.
