Cast Steel Parallel Slide Metal Seated Gate Valve Bolted Bonnet DN15 - DN900

High Pressure Forged Steel Cast Steel Parallel Slide Metal Seated Gate Valve

TEKO Parallel Slide Gate valves have proven pedigree, giving exceptional long life and excellent sealing capabilities over many years. Used in high pressure and high temperature applications, the unique design of the Parallel Slide isolating Gate valve allows it to maintain fluid tightness without the aid of any wedging action thereby eliminating mechanical stresses between the discs when opening or closing the valve. Couple this with the selection of high quality materials, we ensure prolonged life and minimal maintenance for today's power plant operator.

Features

• High performance parallel slide gate valves for isolation of critical water and steam services.
• The tightness of the valve shut-off is due to the pressure of the fluid itself on the disc in contact with the seating surface, rather than friction from closure of the wedge disk on the valve seats.
• A host of advantages over conventional wedge valves.
• No leakage, regardless of temperature or pressure changes.
• Avoids blocking due to thermal binding.
• Options: reinforced valve seats, square gates to increase the valve seat area, V port outlet seat for regulation, protective spool piece to guard against interior component movement in the fully open valve position.
• Double valve format isolation for high-pressure drainage systems: master + martyr.
