An Air pinch valve is a pinch valve. Air or liquid pressure is inserted in the cavity of AIR PINCH VALVE - at the control inlet collapses the internal rubber sleeve to provide immediate and positive shut-off. The rubber sleeve closes completely, even on large particulate matter, abrasive and corrosive materials. When open, the sleeve allows full, unobstructed flow with little turbulence. Air pinch valve sleeves can be easily and economically replaced when they wear out.
1. No metal-to-metal moving parts. No lubri cation ever required. 2. Internal entery stem self-adjusting tfe stem seals for high cycle life. 3. Leaktight tfe body seal unaffected by temperature fluctuations. 4. Large port for higher flow capacity. 5. Four –bolt design with locking fasteners for vibration resis-tance and joint intergrity 6. Extreemely compact design for installation where space is at premium. 7. Insulated handle always shows position of ball. 8. Wide blade drive for maximum ball engagemenet, strength. 9. Double-seal seat design gift repeatable, long life shut- off. 10. Rugged body designed to resist piping stresses and shock.
Double Seal Full Fort Investment Casting Ball Valve
We offer a complete series of Ball control valves with extremely broad range for proportionally controlled application. Included in the series are valves in all commonly used body styles & in a wide selection of construction materials. The rugged design of the valves assures reliable performance under extremes of operating conditions, pipeline stresses, hydraulic & thermal shocks.
We offer a full ball as control element, reduction of flow result from two orifices in series. In the fully open position, each orifices presents a circular profile, it offers no obstruction of flow.
As the valves starts to close, the orifices become smaller and the shape of each goes from circular to elliptical pressure drop is distributed evenly between both orifices. It is advantageous in handing slurries. Fibrous suspensions such as pulp stock. Viscous Fluids, Sludge, Fertilizers Pharmaceuticals, Textiles etc.
Due to highly effective sealing design mirror finish bally, wide stem drive, our Valves offer Cent –Per-Cent positive leak tight shut of in closed position in either direction of flow. With varied pressure and temperature, the unique Tensions seat in our valve automatically varies for required control of flow.
Shreyas Gate Valves are Bolted Bonnet, Rising Spindle, Outside Screw & Yoke Type construction. These Gate valves are available with Solid wedge, Flexible wedge, Split wedge, and Parallel sliding wedge designs offer maximum flexibility and option available to customer for their suitable selection. Gate Valve having Deep stuffing box, which provides assure tightness and maximum packing life. Separate properly machined and lapped back seat facilities are provided for replacement of Gland packing when valve is online & under pressure.
We offer extra long, extended bonnet Gate valve for special services. Antifriction thrust bearing is provided in yoke sleeve for higher sizes and classes.
SHREYAS Gate valves are offered under any Third party inspection.
Gate Valves are available with Gear, Pneumatic Cylinder, Electrical Actuator operated along with accessories like Solenoid, Limit Switch, Air Filter Regulator etc.
To handle highly viscous materials or materials that solidify at ambient temperatures, “Shreyas” can furnish valves with jackets for steam or other heat transfer media to ensure free flow through the valve and to prevent clogging when the valve and to prevent clogging when the valve is closed.
Knife Edge Gate Valve is one of the specific designed valve among other Industrial Valves. This design ensures minimum contact between the parts of the valve thus reducing wear & tear. The high performance Knife Gate Valves features, Non Sliding Motion, Avoid Sliding Contact between Body & Gate and enabling the flushing of media form the valve interior. Bottom edge of the Gate (Knife-Edge) allows the tight shut off even when solid particles settle at the bottom of the body. A wide variety of hardened trim options are available for the Gate, Seat and Wear Ring.
Knife Gate Valves are generally unidirectional valves and act as an excellent hopper isolation valves with their ability to cut through flowing media and closed by dislodging any material in the seating area.
Knife-Edge Gate Valves withstand high temperature & abrasive slurries in Mining, Steel, Power, Chemical, and Paper Industries Ideal for high-density Slurry Lines.

SHREYAS Tubular Type Sight Flow Indicators are Bi-Directional and may be placed in any orientation and easy to check flow from any side of Sight Flow Indicator. It can be installed vertically or horizontally in the middle of any kind of non-transparent pipeline and are very convenient to observe the flow.
We offer sight flow indicators suitable for industrial applications. Sight Flow Indicators provide a quick, reliable and economical way to verify the flow & quality & speed of fluids through industrial process lines. Tubular type Sight Glass is suitable for corrosive chemicals, acids and colored liquids.
Sight Glass are used primarily in processes, where spot indication is desired to detect presence of media, or to inspect color, clarity, turbidity, or other critical characteristics.
Wafer Design Plate Type Check Valve has short face-to-face dimensions and low weight allows a simple space saving installation between the companion flanges. The valves are suitable to mounting between weld neck or slip on type companion flanges of different standards.
They are specially developed for applications where a low-pressure loss is essential. Opening and closing of the valve will take place at an extremely low-pressure difference over the valve disc. The eccentric disc shaft combination with the disc seat guarantees a positive shut off returning media. Wafer check valves are becoming the preferred type of check valve for most applications, due to their compact design and relatively low cost.
Features : Body Type: Single Plate, Short Type Suitable For Horizontal and Vertical Mounting Shorter overall length, mounting requires minimum space. Low Pressure Drop Easy to Install Less Weight Maintenance Free Seat Leakage: Zero Leakage, Tight Shut Off Temperature Range: -250 To + 2000 C.
