摘要：
A friction reducing guide is provided as an insert in the metal gate of a resilient seated gate valve. The gate is encapsulated almost entirely with rubber except forthe guide area. Friction is reduced and any corrosion resistant coating inside the valve body is protected, in the guide area, from excessive abrasion.
