Pump discharge valve facilitate the required operating time at the pump house to arrest at the surge/reversal of flow to pump. Replace two valves (Isolating valve + Non return valve) function in one valve.

Body material Cast Iron, Ductile Iron, Carbon Steel, Stainless Steel, Cast steel

Disc material Ductile Iron, Carbon steel.

Clamping ring material Stainless Steels, Carbon steel.

Seal material EPDM, Nitrile.

FEATURES OF PUMP DISCHARGE VALVES:

Resilient seated Butterfly vales, bi-directional:

Blow-out proof design to ensure no accidental stem push-out takes place under pressure.

Available with a variety of hydraulic actuation.

Adjustable closing time according to surge study can be achieved.

After installation, final tuning / site adjustment of operating time can also be achieved.

Standby pump optional available.

Hand pump during power failure is inbuilt.

Power pack manufacturer only from reputed, proven make.

Hydraulic units in enclosed container only, synchronized with Control panel.

Each Hydraulic operated Butterfly valve tested individually.

Double eccentricity is calculated and provided for each application and not a thumb rule of fixed eccentricity.

MANUAL OPERATED/ELECTRICALLY OPERATED BUTTERFLY VALVES

Body material Cast Iron, Ductile Iron, Carbon Steel, Stainless Steels.

Disc material Ductile Iron, Carbon Steel, Stainless Steels.

Clamping Ring material Stainless Steels, Carbon steel.

Seal material EPDM, Nitrile.

Features OF Manual Operated/Electrical Operated Valve:

Resilient seated Butterfly Valves :

Bi-directional double eccentric soft seated Butterfly valves.

Gearbox and Actuator direct mounting type.

Various types of seal design to facilitate best performance and long seal life.

High performance Double eccentric valves are also available in Wafer and Flanged configurations.

Available with a variety of Pneumatic, Electric and Hydraulic actuation.

We have done FEA analysis for Butterfly valves in order to analyze the behavior of Valve and ensure Design safety and Performance.

Zero Velocity Valve are to prevent reversal / return of water column by perfect non-slam closing just before reversal of water column giving most effective surge control on tripping of pumps in raw water/clear water cross country rising main and lift irrigation schemes.

FEATURES OF THE VALVE

Offered in Flanged end / Butt weld construction for piping connection.

Dome profile designed for steady flow.

Controlled closing characteristics.

Stainless Steel Springs for high sensitivity and low head loss.

Bypass circuit to break the Vacuum arising upstream due to closure of valve.

LIST OF IMPORTANT ORDERS FORZERO VELOCITY VALVES & AIR CUSHION VALVES

These valves are available in non rising as well as rising spindle type suitable for clear water up to 60C. These valves are designed with total compliance with applicable design and testing standards. All designs are validated for stress analysis. Sluice valves find wide application in water works /water /effluent /sewage treatment plants.

FEATURES
