DIN Cast Steel Gate Valve Description

DIN cast steel gate valve

Design standard: DIN3352

Flange standard: DIN2532/DIN2543/DIN2544/DIN2501/EN 1092-1.

Fact to face end: DIN3202 –F4/F5/F7

Inspection and test: DIN3230

Packing seal:

Usually we use flexible graphite, also PTFE or other combined packing material can be used according to buyers. The internal surface of the stuffing box, of which area is contracted with the packing, is of excellent finish(3.2 aarh),can ensure the stem and packing combine close but rolled well.

Body and bonnet connection.

PN10 TO PN64 by bolted bonnet(B&B),PN100 to PN320 use pressurized seal design.

Actuation: usually use hand wheel and worm gear box. Can use chain wheel and electric actuator according to buyers.

Design of disc:

For size 2 inch and above,we use flexible wedge(flexible gate),for 2 inch and below, use solid wedge(solid gate)

Back seat design

All our gate valves have back seat design. Normally, the carbon steel gate valve is fixed with a renewable backseat, for stainless steel gate valve, the backseat is machined directly in the bonnet or machined after welding. When the gate valve is at full open position,the sealing of the backseat can be reliable.

 Stem design:

The stem is of integral forged design. The connection of stem and disc is T type. The strength of connecting area is stronger than the T threaded part of stem.  .

Stem nut design.

Usually ,the stem nut is made of ASTM A439 D2, also can be changed as per buyer’s request. For large size gate valve, rolling bearing is fixed between nut and stem, which can reduce torque and make gate valve easy to open.

Seat design:

For carbon steel gate valve,the seat is usually forged steel. For stainless steel gate valve, usually use integral seat.Sealing face of the seat can be spray welded hard alloy if specified by buyers. Renewable threaded and welded on seat can also on optional.
