The valve furth er comprises first (18) and second gates (20) located within the housing, th e gates being movable in different directions transverse to the throughbore between the throughbore open position and the throughbore closed position. M ovement of the gates from the throughbore open position to the throughbore c losed position, in use, shares a tubular located between the gates. The valv e also comprises a first seal seat (22) performing a seal of one of the gate s in the throughbore closed position to seal the throughbore.
