Product Advantage

Standard AISI304 or 316 stainless steel gate is grinded and polished smoothly as mirror, which can effectively avoid damage of packing and seat through opening or closing and make a greater seal. The bottom of the gate edge is machined to a bevel, so that it cuts through the solids for a tighter seal in closed position. A knife protector can be provided for additional protection against dust.

There are 3 features as below:
1. Standard seat NBR, EPDM, also available in PTFE, Viton, Silicone etc. Unique design that mechanically locks the seal in the internal of valve body with a stainless steel retainer ring. Normally it is unidirectional seal design, and bidirectional seal as requested.
2. Several layers of braided packing with an easy access packing gland ensuring a tight seal. Available in a range of materials: Graphite, PTFE, PTFE+KEVLAR etc.
