Kinvalve: Your Reliable Stainless Steel Gate Valve Manufacturer
Kinvalve ss gate valves are known for their toughness and corrosion resistance, while SS304 and SS316 are the most popular choices for Kinvalve stainless gate valves.
As a Kinvalve stainless steel gate valves can be designed with different configurations to suit your different application requirements.
Connection between Body and Bonnet
Generally, there are screwed bonnets for threaded stainless steel gate valves or bolted bonnets for stainless steel flanged gate valves.
Stem Nut
At Kinvalve, you can choose the stem nut from the materials of bronze alloy or ASTM A439 D2(Austenitic nodular cast iron). These two alloys have the benefits of resistance to heat, corrosion and wear.
Gasket of Bonnet
Gasket of the bonnet is the last defense to prevent leakage from the bonnet. You can customize it in pure PTFE or stainless steel combined with flexible graphite for your specifics.
Seat
At Kinvalve, in the case of stainless steel gate valve, an integral seat is usually standard. And hard alloy overlay integrally also can be your option. At your request, we provide the renewable threaded or welded on the seat as well.
Backseat
At Kinvalve, all our gate valves always have a back seat design. A back seat is a seating arrangement inside the bonnet. When the gate valve is fully open, the valve stem ‘back seats’ against the bonnet and closes off pressure to the stuffing box.
This essentially serves as a backup to the primary seal on the valve that is most often a stuffing box sealed with compression packing. At Kinvalve, the intent of this design is to allow a user to re-pack a valve on-line without having to shut down the system in which the valve is being used.
Stem Packing
At Kinvalve, you can decide your gate valve with either molded flexible graphite or PTFE(including combined PTFE) as stem packing material.
Although our bolted bonnet design allows you to easily replace stem packing, the proper packing material and good design will allow you to have a stainless steel gate valve with less leakage and longer service life.
Kinvalve offers an impressive selection of stainless steel gate valves to meet your specification. We currently offer DIN gate valves, including PN 10, and PN 16 pressure ratings.
And we also offer Class 150 gate valves in NRS and OS&Y arrangements with a bolted bonnet as well as JIS Gate Valves.
