SHUT OFF VALVES

 

Butterfly valves (rubber seat type)
Applicable diameter: Equal or more than 200 mm

 
Butterfly valves (rubber seat type)
Morita’s Butterfly valve (rubber seat type) is a valve complies with JWWA B 138 Standard.
The face-to-face dimensions of the valve are the same one as JIS B 2062.
Due to the disc being inclined, the disc seat structure can be simple while keeping shut off performance, and that makes easy steering, durability and maintainability.
For the disc seat O-ring, a stainless-steel core is applied.
That generates excellent prevention against peeling and shedding, and it results higher shut off performance and durability.
We solicit to use this valve for water distribution facilities of treated water supply, sewage, industrial water supply and agricultural water supply.
Product Features
  • Disc inclined construction makes easy steering and easy maintenance
  • Because of a stainless-steel core type disc seat, high shut off performance and durability are obtained at the disc portion

Metal seat type butterfly valves
Applicable diameter: Equal or more than 200 mm

 
Metal seat type butterfly valves
The Metal seat type butterfly valve is developed to withstand harsh conditions of use, such as strong in biting and seizure even in repetition of opening and closing by mounting stainless steel (JIS SUS304) for the body portion and special stainless steel for the disc considering higher corrosion resistance and higher durability.
Due to the construction being less complicated in the neck portion of the stem, and the operation being easy and less fluid leakage by adopting flexible seat on the disc part, the valve has excellent shut off performance.
We solicit to use this valve for water distribution facilities of treated water supply, sewage, industrial water supply and agricultural water supply.
Product Features
  • Excellent water shut off performance and easy operation at the opening and closing
  • Can be used even in harsh conditions
  • The face-to-face dimensions and flange sizes of the valve are the same ones as the normal butterfly valve as per JWWA B 138 standard

Easy connecting butterfly valves
Applicable diameter: Equal or more than 200 mm

 
Easy connecting butterfly valves
Morita’s Easy connecting butterfly valve is a valve corresponding to “stretch, deflection, and torsion” of piping in addition to the functions of normal butterfly valve.
The adjustable joint portion and the inclined type disc structure have high sealing performance.
The face-to-face dimensions of Japanese normal valves can be applied to this valve.
Accordingly, it is ideal not only for replacement with the existing valve but also for installation the valve newly.
This valve corresponds as various butterfly valves such as Metal seat type, Pre-filling wing type, and Pre-filling integral bleed port type.
We solicit to use this valve for water distribution facilities of treated water supply, sewage, industrial water supply and agricultural water supply.
Product Features
  • This valve corresponds to “stretch, deflection and torsion” of piping
  • High sealing performance at the adjustable joint portion and the inclined type disc
  • Can be installed in a small space
  • Corresponds to various types of butterfly valve

Pre-filling integral bleed port type butterfly valves
Applicable diameter: Equal or more than 200 mm

 
Pre-filling integral bleed port type butterfly valves
Morita’s Pre-filling integral bleed port type butterfly valve is a rationalized valve in which a small sub-valve is added into a main valve and has functions like setting two valves.
The sub-valve is a ball valve, whose seat does not jump out even under the high velocity and is hard to cause the cavitation.
The face-to-face dimensions of this valve conform to the water-supply purpose butterfly valve (as per JWWA B 138 standard).
Further, the valve employs the inclined disc, therefore, is excellent in the aspect of water shut-off performance and operability.
We solicit to use this valve for water distribution facilities of treated water supply, sewage, industrial water supply and agricultural water supply.
Product Features
  • Control of small flow by the bleed port is possible
  • Smooth pre-filling can be achieved by the bleed port
  • Less-space installation by the built-in by-pass function
  • Employs a ball valve for adjusting flow amount
  • Separate operating shafts for control of the main valve and the bleed port
  • Simple main valve construction having excellent water shut-off performance

Outside screw type sluice valves
Applicable diameter: Equal or more than 300 mm

 
Outside screw type sluice valves
Morita’s Outside screw type sluice valve complies with the JWWA B 122 and JIS B 2062 Standards.
The sluice valve employs ductile cast iron in the body part, and stainless steel in the stem part, therefore, has ample durability, abrasion resistance, and corrosion resistance.
We solicit to use this valve for water distribution facilities of treated water supply, sewage, industrial water supply and agricultural water supply.
Product Features
  • The screwed stem does not bite any foreign materials because it is not inside of the valve
  • The stem part is possible to re-charge lubricant, therefore, it suits in case of repeat action by electric actuator
  • The pressure loss is small because the disc part does not remain in the flow at the time of full opening
  • One-side-inclined type disc part is employed to prevent the vibration which will be caused by the turbulence occurred by the pump and so on
