Working principle of the VE Dual Expanding Plug Valve

	Valve is open When the valve is fully open, both seals are protected from the flow path
	Valve is closing plug is rotating Valve plug and slips rotate to place seals in closing position, during rotation there is no contact between the body and seals.
	Valve is almost closed expansion of the slips Once the plug has rotated 90°, the slips expand onto the body seats without causing any wear or abrasion to the seals.
	Valve is closed Double Block & Bleed The elastomer seals are fully compressed.
