Note:
1.The above 'WET' means the test fluid is water or other non-lubricating mediums. 'DRY' means the test medium is dry compressed air.
2.When the valve serves in a too low working temperature, operating torque will increase with the consequence of increased hardness of rubber in low temperature.
