1. High Tension Coil Spring
Ensures a stable seal at upper and lower gland even at extreme temperatures or when thermal shock occurs
2. Minimum 3mm PFA Thickness
Seam free PFA injection moulding on the seat and disc to a minimum thickness of 3mm prevents permeation of dangerous fluids or gases
3. No Special Gasket Needed
Stable flange sealing performance is ensured by concentric circular grooves on the flange faces thereby eliminating the need for a special gasket when operating under specified temperatures. The wider sealing area also ensures minimum "creep" at high temperature. Flange sealing mechanism is independent from the seating and gland seals ensuring there is no loss of the line fluid.
4. Total Sealing
Valve structure includes primary, secondary and independent tertiary seal - ie. gland packing. There is also a fourth seal of 0-rings on the top/bottom stems - ie. dust seal.

Characteristics:
Japan Patent No1769954(40-300mm)
An original design with a spherical inner surface of the body contacting to spherical ends of the disc hub allows its self-alignment. This design ensures prevention of over-run of the disc.
(350-600mm) A spacer ring is provided between each end of the disc hub and the inner surface of the body for self-alignment of the disc. The over-run of the disc is prevented by a protrusion on the inner surface of the body.
Disc with thin but highly stiff rib:
(40-300mm) The disc has a thin, but highly stiff rib.
(350-600mm) The rib of disc has a convex figuration like an end plate of a tank. Either design has successfully reduced thermal expansion and shows a constant sealing capability against changes in temperature or pressure of fluid.
Double Eccentric Structure:
When the disc rotates, it unseats at a small open angle, by its cam effect. It prevents seat abrasion and provides perfect shut-off for a long period.
Seal the flow from both directions:
The valve can seal in reverse flow as well as the preferred direction, and cope with the flow direction changes. The ball lock method is adopted to facilitate the easy replacement of the seat ring. Metal seat and Teflon seat are both quickly replaceable.

Remote Control Valve:
Hayward's Pneumatically Actuated Diaphragm Valves are designed for the reliable, remote control of liquids in piping systems. They are suitable for both clean and slurry type fluids at pressures up to 150 PSI.
Position Indicator:
You never have to guess if a Hayward Diaphragm Valve is in the open or closed position. A visual position indicator comes standard with every valve.
Powerful Actuator:
The actuator used to operate the valve, while lightweight and compact, is still powerful enough to open and close the valve at all internal pressures up to the full rated pressure of the valve,150 PSI.
No Corrosion Problems:
Hayward's Diaphragm Valves stand up to the most aggressive fluids and they will never rust, corrode or contaminate the process fluid. Even the actuator housing is plastic and requires no failure prone coating or painting.
Modular Options:
Several modular design options are available. This concept is very cost effective because the actuator can be configured exactly for a specific application using only the options required. You never have to pay for options you do not need.

Based upon model tests, the lens type and lattice door ( through flow ) type valves are optimized and a minimum flow head loss coefficient of 0.07 can be guaranteed.
This type of valve is mainly used as safety valve or as a turbine inlet valve and pump valve. They are operated by oil hydraulic systems for opening and closing or closing weight and hydraulic pressure for opening. For turbine inlet valves oil pressure can be taken also from the governor hydraulic oil system. The sealing system is of flexible adjustable type - rubber/metal or metal/metal. The lattice door type valves can be also equipped with a maintenance seal. The hydraulic and electric / electronic control system is part of the delivery. Auxiliary equipment like bypass, air and vacuum valve, pipe rupture device, connecting pipes are usually in the scope of supply. Water flow through the valve in both directions is principally possible.
